Description

25-Hydroxydihydrotachysterol(2) is a synthetic analog of vitamin D, specifically a hydroxylated derivative of dihydrotachysterol. This compound is significant for its role in research and development within the pharmaceutical and life sciences sectors, particularly in studies related to calcium metabolism, bone health, and vitamin D receptor activity. It is primarily needed by research institutions, pharmaceutical companies, and fine chemical manufacturers engaged in developing novel therapeutics or analytical reference standards.

Application

• Pharmaceutical Research & Development: A key intermediate or reference standard in the synthesis and study of vitamin D analogs and metabolites.
• Biochemical Research: Used to investigate calcium and phosphate homeostasis, bone mineralization pathways, and parathyroid hormone function.
• Reference Standard: Serves as a high-purity calibration standard for analytical methods such as HPLC and LC-MS in quality control laboratories.
• Metabolic Studies: Employed in preclinical studies to understand the metabolism and biological activity of vitamin D-related compounds.
• Fine Chemical Synthesis: Acts as a specialized building block for the preparation of more complex, biologically active molecules.

Quality Control

Our 25-Hydroxydihydrotachysterol(2) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods and purity assessment by chromatography, to ensure it meets the high standards required for research applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) or as specified on the label or COA. This material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
