Description

25-Hydroxytachysterol3 CAS NO 39932-44-0 is a synthetic analog of vitamin D, specifically a hydroxylated derivative of tachysterol. This compound is significant for its role in research focused on calcium metabolism, bone health, and the vitamin D endocrine system. It is primarily needed by pharmaceutical R&D laboratories, academic research institutions, and manufacturers of fine chemicals and reference standards for analytical and developmental purposes.

Application

• Pharmaceutical Research & Development: A key intermediate and reference standard in the synthesis and study of novel vitamin D analogs and metabolites.
• Biochemical Studies: Used to investigate the mechanisms of vitamin D action, receptor binding, and gene regulation in cellular and in vitro models.
• Metabolic Pathway Analysis: Serves as a tool compound for studying the hydroxylation pathways and biological activity profiles of vitamin D-related sterols.
• Fine Chemical Synthesis: Employed as a building block for the preparation of more complex, biologically active secosteroids and research compounds.
• Analytical Standard: Used as a high-purity reference material in HPLC, LC-MS, and other chromatographic methods for qualitative and quantitative analysis.

Quality Control

Our 25-Hydroxytachysterol3 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets rigorous research-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for your critical research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation.
