English description（英文原文，共 1110 字符）
Product Name:Retinoic acid
English Name:Retinoic acid
CAS No.:302-79-4
Aliases:Tretinoin, Vitamin A acid, all-trans-Retinoic acid, ATRA
Molecular Formula:C20H28O2
Physical Properties:Yellow to light orange crystalline powder; melting point 180-182°C; density approximately 1.02 g/cm³; practically insoluble in water, slightly soluble in ethanol, soluble in chloroform, ether and oils. Light-sensitive, prone to oxidative decomposition when exposed to light and air; should be kept tightly sealed and protected from light.
Uses:Retinoic acid is a key active metabolite of vitamin A that regulates cell proliferation and differentiation. It is widely used in dermatology for the treatment of acne, photoaging-related skin disorders and abnormal keratinization. In oncology research, it induces differentiation and apoptosis of acute promyelocytic leukemia cells. It also serves as a cell differentiation inducer in biochemical and molecular biology studies.
Technical Specifications:
Assay (HPLC) ≥98.0%
Melting point range 180-182°C
Loss on drying ≤0.5%
Residue on ignition ≤0.1%
Heavy metals ≤20ppm
