7-dehydrocholesterol uses and synthesis methods7 - dehydrocholesterol is a kind of white crystalline powder, light yellow crystalline powder. 7 - dehydrocholesterol is extracted from pig skin, and can also be obtained from cholesterol through acylation, oxidation, hydrazone, hydrazone and saponification. 7 - dehydrocholesterol is a kind of pharmaceutical intermediate synthesized by saponification reaction. Purpose 7 - Dehydrocholesterol Purpose: 1. Chemicalbook, an important intermediate in the synthesis of vitamin D3. 2. Additives in skin care and sunscreen cosmetics. 3. Chemical properties of other laboratory reagents, flake crystals (methanol aqueous solution/ether). Melting point 150-151 ℃ (anhydrous). [ α] 20/D-113.6 ° (chloroform). It is easy to oxidize in exposed air. Uses The intermediate of vitamin D3. Production method: Cholesterol can also be extracted from pig skin through esterification, bromination, elimination and hydrolysis.
