Description

7-Dehydrocholesteryl Benzoate is a high-purity, synthetic sterol derivative, specifically the benzoate ester of 7-dehydrocholesterol. This compound serves as a crucial advanced intermediate in the synthesis of Vitamin D3 and its analogs, valued for its defined chemical structure and reactivity. It is primarily required by pharmaceutical R&D laboratories, fine chemical manufacturers, and academic institutions engaged in steroid chemistry and nutraceutical development.

Application

• Key Intermediate for Vitamin D3 Synthesis: Acts as a critical precursor in the industrial and laboratory-scale production of cholecalciferol (Vitamin D3).
• Pharmaceutical Research: Used in the development and study of new Vitamin D analogs and related steroidal therapeutics.
• Reference Standard: Serves as an analytical standard in HPLC and GC methods for quality control in pharmaceutical and nutraceutical manufacturing.
• Biochemical Studies: Employed in research investigating cholesterol metabolism, photochemistry, and steroid hormone pathways.
• Fine Chemical Synthesis: Utilized as a building block for the synthesis of other complex sterol derivatives and specialty chemicals.
