Dermorphin (CAS 77614-16-5) is a high-purity opioid peptide agonist API, a potent heptapeptide derived from amphibian skin secretions. It selectively binds to μ-opioid receptors to exert a strong analgesic effect, with higher potency and specificity than traditional opioid analgesics. Its refined powder form ensures consistent bioactivity and ultra-low impurity profiles, making it a reliable active ingredient for pain management pharmaceutical R&D.
