Tretinoin EP Impurity C, also known as 11,13-di-cis-Retinoic Acid, is a stereoisomeric reference standard used in pharmaceutical quality control. Its molecular formula is C20H28O2 and CAS number is 6524-46-7. This compound is typically synthesized via photo-isomerization of all-trans-retinoic acid to ensure high purity for analytical calibration.
This substance requires storage at -20°C under inert atmosphere to prevent oxidation. Strict handling protocols are mandatory due to potential teratogenicity; personnel must wear appropriate PPE including gloves and eye protection to avoid direct contact or inhalation.
