Product Name: Paricalcitol intermediate
CAS No.: 957214-02-7
Quality Standard: Enterprise standard, content NLT 98%
Main Application: Synthesis of Paricalcitol
Paricalcitol intermediate-2 is a key synthetic precursor in the manufacturing of Paricalcitol (19-nor-1,25-dihydroxyvitamin D2), an active vitamin D analog. The core process involves selective photochemical irradiation and chemical modification of specific steroid derivatives to achieve the required stereochemistry. Molecular Formula: C27H40O3; CAS No.: 163863-82-1.
Strictly controlled storage under inert atmosphere at -20°C to prevent degradation. Handling requires PPE due to potential skin irritation. Clinical use is limited by strict dosage protocols to avoid hypercalcemia and vascular calcification risks.
