Sermorelin (also known by its Chinese alias, Sermorelin Acetate; foreign names include Sermorelin, SERMORELINA, SERMORELINE, etc.) is a peptide-based chemical substance. Its chemical formula is C₁₄₉H₂₄₆N₄₄O₄₂, its molecular weight is 3357.88, and its CAS Registry Number is 86168-78-7. It is classified as a growth hormone-releasing hormone (GHRH) analog, corresponding to the 1-29 fragment of endogenous human GHRH.
This substance appears as a white powder, with a density of 1.5±0.1 g/cm³, a refractive index of 1.650, and a LogP value of -3.92. It requires airtight, dry storage at -20°C to prevent its stability from being compromised by acidic or alkaline environments. As a signaling pathway-related peptide, Sermorelin functions by stimulating the pituitary gland to promote the production and release of growth hormone; it is primarily utilized in the diagnostic assessment of growth hormone secretion and within the field of sports performance enhancement. Its acetate form carries the CAS Registry Number 114466-38-5, features a LogP value of 5.07, and exhibits a purity range of 98.9% to 99.0%.
