Product Overview
α-MSH (CAS 581-05-5) is a synthetic peptide widely utilized in biochemical research and cosmetic formulations for pigment regulation studies and anti-inflammatory research. It acts as an endogenous peptide agonist that selectively targets melanocortin receptors to stimulate melanogenesis. Conscientia Industrial synthesizes high-purity α-MSH through advanced solid-phase peptide synthesis (SPPS) technology followed by multiple liquid chromatography purification steps.
