AOD-9604 Sequence, Molecular Weight & Chemical Identity

3 min read•Published 2025-03-27•Quality Peptide USA Research

AOD-9604 is a modified synthetic 16-amino-acid fragment corresponding to residues 176–191 of the C-terminus of human growth hormone, with an added N-terminal tyrosine for stability. It is studied in adipose-tissue and lipolysis research.. This guide covers sequence & structure for AOD-9604 — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.

Primary Sequence

The primary sequence of AOD-9604 is recorded as: Tyr-hGH(177-191). Sequence integrity is verified during release testing using analytical reverse-phase HPLC compared against a reference standard, with mass spectrometry confirming the expected molecular ion.

Molecular Formula and Weight

AOD-9604 carries the molecular formula C78H123N23O23S2 and a calculated monoisotopic weight of approximately ≈ 1817.07 g/mol. These values are essential for accurate molar-concentration calculations during reconstitution and for normalizing dose curves across studies.

Identifiers and Synonyms

CAS Registry: 221231-10-3. AOD-9604 is also referenced in the literature under its full chemical name and developmental designations. When searching publications, querying both the common and chemical names typically surfaces the broadest body of work.

Structural Notes for Researchers

AOD-9604 is supplied as a lyophilized solid with a white to off-white appearance. Researchers should reconstitute in sterile bacteriostatic water unless their assay calls for a specific buffer (e.g., 0.1% acetic acid for hydrophobic peptides). Quality Peptide USA publishes the full chemical-identity card on every product page so that incoming-QC checks can be performed against a known reference.
