AOD-9604 Supplier with COA | High-Purity Research Peptide

Understanding AOD-9604 as a Research Peptide

AOD-9604 is a synthetic peptide fragment structurally derived from the C‑terminus of human growth hormone (hGH), corresponding to amino acid residues 177–191. This peptide has attracted interest in biometabolic research due to its capacity to interact with lipid metabolism and associated cellular signaling pathways without triggering the broader endocrine activities of full‑length hGH. Investigators study AOD-9604 in in vitro models and in in vivo laboratory settings to explore mechanisms such as lipolysis, oxidation of free fatty acids, and the modulation of insulin‑sensitive signaling cascades.

For experimental use, AOD-9604 is supplied as a sterile lyophilized powder. This presentation helps preserve peptide integrity during long‑term storage by minimizing hydrolytic degradation. Prior to application, researchers reconstitute the peptide in sterile water or an appropriate buffer solution, taking care to follow recommended solubilization protocols that may include gentle agitation and avoidance of vigorous vortexing to maintain structural stability. The reconstituted peptide can then be utilized in cell‑based assays, receptor‑binding studies, or animal model investigations, always in accordance with institutional biosafety and ethical guidelines.

All AOD-9604 products offered are intended strictly for laboratory research purposes. They are not manufactured, tested, or certified for human or veterinary administration, clinical use, or any diagnostic procedure. Researchers must ensure that their work complies with all applicable local, national, and international regulations governing the handling and disposal of research‑only biochemicals.

The Critical Role of a Certificate of Analysis (COA) for Research Peptides

A Certificate of Analysis, commonly abbreviated as COA, is a formal document issued by the manufacturer that supplies verified, batch‑specific data on a peptide’s identity, purity, and impurity profile. For any laboratory relying on AOD‑9604 in controlled experiments, the COA is not a mere formality—it is a foundational element of experimental reproducibility. Without accurate knowledge of purity, residual solvents, and enantiomeric or chemical impurities, interpretation of biological results can be confounded.

Key parameters documented on a research‑grade COA include:

High‑performance liquid chromatography (HPLC) purity: Typically, a value of ≥98% ensures that the principal component overwhelmingly represents the desired peptide, minimizing off‑target effects from synthesis‑related impurities.
Mass spectrometry (MS) confirmation: Electrospray ionization (ESI‑MS) or matrix‑assisted laser desorption/ionization (MALDI‑TOF) data validate that the observed molecular mass matches the theoretical monoisotopic mass, confirming correct sequence assembly.
Peptide content: Quantitative amino acid analysis or nitrogen determination provides the net peptide amount, accounting for counterions and residual moisture—critical for accurate molarity in biochemical assays.
Residual solvent and trifluoroacetic acid (TFA) content: These values indicate trace process solvents and the level of TFA counterion that may remain after purification, which can influence cell viability in sensitive assays.

Researchers routinely match batch‑specific COAs to their experimental records to enable inter‑study comparisons and to identify any variability that could arise from changes in synthesis or purification protocols. A reputable AOD‑9604 supplier with COA will make these documents readily accessible—often through a secure online portal where the batch number printed on the vial label can be entered to download the corresponding documentation.

Criteria for Selecting a Dependable AOD-9604 Supplier

Choosing a reliable source for research‑grade AOD‑9604 demands careful evaluation of the supplier’s quality infrastructure and transparency. The following criteria help research procurement professionals and principal investigators navigate the market:

Comprehensive, batch‑specific COAs: Confirm that the supplier issues a detailed COA generated by an accredited analytical laboratory for every production batch. The COA should include HPLC chromatograms, mass spectra, and quantitative purity data—not just a summary report.
Transparent quality control workflows: Inquire about the range of analytical techniques employed. A rigorous program will include orthogonal methods: reversed‑phase HPLC for purity, ESI‑MS or MALDI‑TOF for mass verification, and amino acid analysis for composition and peptide content. Some suppliers may also offer N‑terminal sequencing for added identity confirmation.
Manufacturing standards: Although peptides for research are not regulated as pharmaceutical ingredients, suppliers that operate under GMP‑like conditions—using certified reference materials, documented cleaning procedures, and controlled environments—reduce the risk of cross‑contamination and lot‑to‑lot variability.
Community standing: Evaluate the supplier’s track record within the research community. Feedback from university laboratories, pharmaceutical R&D departments, and distributors, as well as citations in peer‑reviewed literature, can indicate consistent reliability. A supplier that openly addresses technical inquiries and provides additional analytical data upon request demonstrates a commitment to supporting high‑quality science.

When assessing an AOD‑9604 supplier with COA, requesting a sample COA prior to purchase is a reasonable step. A transparent supplier will provide an anonymized example or a current batch document for evaluation, enabling you to verify the depth of testing before committing to a procurement.

Our AOD-9604 Product Specifications with Full COA

Our AOD‑9604 is provided as a white to off‑white lyophilized powder, with a molecular weight of approximately 1817.0 Da calculated for the acetate salt form. Each batch is rigorously characterized, and the following specifications are typical of the quality documented on the accompanying COA:

Appearance: White lyophilized powder.
Purity by HPLC: ≥98% (measured at 214 nm), with the main peak accounting for the specified material and related impurity peaks individually reported.
Mass spectrometric identity: The observed monoisotopic mass corresponds to the theoretical value within an expected mass accuracy window (±1 Da for ESI‑MS; ±0.1% for MALDI‑TOF).
Peptide content: Determined by amino acid analysis or elemental nitrogen analysis; typical values fall between 70% and 85%, reflecting the contribution of residual water and counterions. This value is essential for calculating the net peptide concentration.
Residual TFA: Usually <1% as determined by ion chromatography or HPLC, unless otherwise agreed for specific research requirements.
Solubility and handling instructions: Detailed recommendations for reconstitution are included in the product datasheet and COA, covering compatible solvents and typical concentrations used in research protocols.

The COA delivered with each order includes full analytical traces: the HPLC chromatogram with integration results, the mass spectrum, and—where applicable—the amino acid analysis report. These are linked irrevocably to the batch number printed on the vial, ensuring full traceability.

Quality Assurance and Testing Procedures

Every batch of AOD‑9604 passes through a systematic suite of release tests conducted in a quality‑controlled laboratory. This multi‑step approach ensures that the peptide meets predefined acceptance criteria and that any batch‑specific deviations are identified and documented.

Reversed‑phase HPLC: A C18 column and a linear gradient of acetonitrile in water (with 0.1% TFA) are used to resolve the principal peptide from synthesis‑related impurities. Purity is calculated as the area percent of the main peak relative to total integrated area. Chromatograms are scrutinized for shoulders, pre‑peaks, or tailing that could indicate degradation or aggregation.
Mass spectrometry: Either ESI‑MS or MALDI‑TOF MS is performed. The mass spectrum must show a dominant signal corresponding to the singly or multiply charged ion of the target peptide, with no unexplained signals at >5% relative intensity that cannot be assigned to adducts or minor charge states.
Amino acid analysis: The peptide is hydrolyzed in acid, and the liberated amino acids are derivatized and quantified. This test confirms the correct molar ratio of amino acids, thereby independently validating the peptide sequence and providing the absolute peptide content.
Optional tests: Upon request, we can perform sterility testing (according to USP principles) and bacterial endotoxin determination (by LAL assay) for applications requiring minimized biological burden, such as cell‑based assays where microbial contaminants could introduce artifacts.

All testing data is reviewed by a dedicated quality unit before batch release. This process ensures that every AOD‑9604 shipment is accompanied by a COA that genuinely reflects the quality of the product inside the vial.
