Description

19-Hydroxycholestenone is a specialized oxysterol derivative, a key intermediate in the biosynthesis of steroid hormones and bile acids. This compound is of significant value in biochemical research and pharmaceutical development for studying metabolic pathways and enzyme activities. It is primarily utilized by research institutions, pharmaceutical R&D departments, and fine chemical manufacturers involved in steroid chemistry and metabolic disorder research.

Application

• Biochemical Research: Critical intermediate for studying cholesterol metabolism and the enzymatic pathways involving cytochrome P450 enzymes.
• Pharmaceutical R&D: Used as a reference standard and building block in the development of novel therapeutic agents targeting metabolic diseases.
• Enzyme Activity Studies: Serves as a substrate for investigating the function and kinetics of hydroxysteroid dehydrogenases and other steroid-modifying enzymes.
• Analytical Standard: Employed as a high-purity calibrant in chromatographic (HPLC, GC-MS) and spectroscopic analyses for accurate quantification in complex matrices.
• Metabolite Synthesis: A precursor in the synthetic pathways for producing other biologically active oxysterols and steroid hormone analogs.
