Description

Retinol, Hexadecanoate, (9-Cis,13-Cis)- (9Ci) CAS NO 34356-30-4 is a specific, high-purity ester derivative of retinol (Vitamin A). This compound is valued for its enhanced stability compared to free retinol, making it a critical intermediate in advanced pharmaceutical and cosmetic formulations. It is primarily sought by manufacturers in the nutraceutical, cosmeceutical, and fine chemical synthesis sectors for developing products requiring precise stereochemistry and reliable performance.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized retinoid-based therapeutics and prodrugs.
• Cosmetic Actives: A key ingredient in high-end anti-aging serums, creams, and treatments where stabilized Vitamin A activity is required.
• Nutraceutical Formulations: Incorporated into advanced dietary supplements and functional foods designed for targeted delivery.
• Biochemical Research: Serves as a standard or reagent in studies of retinoid metabolism, signaling, and isomer-specific effects.
• Fine Chemical Synthesis: Acts as a building block for creating novel compounds with tailored biological activity in agrochemical and material science research.
