Description

4'-Apo-β,ψ-Caroten-4'-Oic Acid Methyl Ester is a specialized carotenoid derivative, a methyl ester of the corresponding apo-carotenoic acid. This compound is valued for its role as a key intermediate and reference standard in the synthesis and analysis of higher-value carotenoids and retinoids. It is primarily required by research institutions and manufacturers in the pharmaceutical, nutraceutical, and fine chemical sectors for developing novel compounds and analytical methods.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of retinoid-based drugs and specialized carotenoid analogs for therapeutic research.
• Reference Standard: Used as a high-purity analytical standard in HPLC and LC-MS methods for quality control of carotenoid products and metabolic studies.
• Nutraceutical Research: Employed in the development and study of novel provitamin A compounds and antioxidant formulations.
• Biochemical Research: Utilized in studies of carotenoid metabolism, cleavage enzymes, and the biological activity of apo-carotenoids.
• Fine Chemical Synthesis: Acts as a starting material or intermediate for the custom synthesis of complex organic molecules with specific chromophore properties.
