AOD9604 is a synthetic 16-amino acid peptide corresponding to residues 177–191 of its parent sequence, carrying an N-terminal tyrosine in place of the phenylalanine found at position 176. It has the molecular formula C₇₈H₁₂₃N₂₃O₂₃S₂, a molecular weight of 1,815.1 g/mol, and CAS number 221231-10-3, and contains an intramolecular disulfide bridge that constrains its conformation. It differs from the unmodified 176-191 sequence by a single oxygen atom — 1,815.1 versus 1,799.1 g/mol — a difference that cannot be resolved by HPLC purity analysis alone. Supplied as a white to off-white lyophilized powder, readily soluble in water; keep refrigerated at 36‑46 °F (2‑8 °C). This product is strictly for research purposes only.

AOD9604 may require 0.6% acetic acid solution for reconstitution. Research Water may cause gelling and is not included for free with this product.
