Product Name:Doxercalciferol Intermediate
English Name:Doxercalciferol Intermediate
CAS No.:111594-58-2
Aliases:Silane, [[(1a,3b,5E,7E,22E)-9,10-secoergosta-5,7,10(19),22-tetraene-1,3-diyl]bis(oxy)]bis[(1,1-dimethylethyl)dimethyl- (9CI)
Molecular Formula:C40H72O2Si2
Physical Properties:White to off-white solid or viscous liquid. Density approximately 0.92 g/cm³, boiling point approximately 585.5°C (predicted), flash point approximately 265.4°C. Insoluble in water, soluble in dichloromethane, ethyl acetate, tetrahydrofuran and other organic solvents. Sensitive to acid and alkali; the silyl protecting group is readily removed under acidic conditions. Avoid contact with strong oxidizing agents.
Uses:This product is a key intermediate in the synthesis of doxercalciferol, a vitamin D2 analog used clinically for the treatment of secondary hyperparathyroidism. The intermediate contains silyl protecting groups that shield hydroxyl functionalities during the synthetic sequence, enabling selective reactions, and the target product is obtained upon final deprotection.
Technical Specifications:
Purity (HPLC) ≥ 98.0%
Appearance: White to off-white solid
Water content (Karl Fischer) ≤ 0.5%
Specific rotation [α]D20 = +30° to +40° (c=1, chloroform)
Storage: Store under nitrogen, protected from light at −20°C
