Description

25-Hydroxydihydrotachysterol(3) CAS NO 25631-39-4 is a synthetic analog of vitamin D, specifically a hydroxylated derivative of dihydrotachysterol. This compound is of significant value in pharmaceutical research and development due to its role in studying calcium and phosphate metabolism, as well as its potential applications in treating bone disorders. It is primarily needed by research institutions, pharmaceutical manufacturers, and fine chemical suppliers focused on developing treatments for conditions like hypoparathyroidism, renal osteodystrophy, and vitamin D-resistant rickets.

Application

• Pharmaceutical Intermediate: Serves as a key synthetic precursor in the production of advanced vitamin D analogs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard and experimental compound in studies of vitamin D receptor (VDR) activation and calcium homeostasis.
• Metabolic Disorder Studies: Applied in preclinical research for investigating and modeling bone metabolism diseases.
• Analytical Standard: Employed as a high-purity certified reference material (CRM) for quality control and method validation in analytical laboratories.
• Nutraceutical Development: Explored for potential use in advanced dietary supplements targeting bone health, subject to regulatory approval.
