Description

Dihydrocholesterol is a saturated sterol derivative, also known as cholestanol, which serves as a key intermediate and reference standard in biochemical research and synthesis. This compound is valued for its structural role in studying cholesterol metabolism, membrane biophysics, and the biosynthesis of other steroid hormones. It is primarily utilized by research institutions, pharmaceutical development labs, and fine chemical manufacturers involved in steroid chemistry and lipid analysis.

Application

• Biochemical Research: Used as a critical intermediate and reference standard in studies of cholesterol biosynthesis, absorption, and metabolic pathways.
• Pharmaceutical Development: Serves as a starting material or intermediate in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs).
• Analytical Standard: Employed as a high-purity standard in chromatographic methods (HPLC, GC) for the quantification and qualification of sterols in various matrices.
• Membrane Studies: Utilized in biophysical research to investigate the effects of saturated sterols on membrane fluidity, structure, and function.
• Fine Chemical Synthesis: Acts as a versatile building block for the preparation of specialized steroidal compounds for research and industrial applications.
• Nutraceutical Research: Investigated for its potential role and effects in nutritional and dietary supplement studies related to lipid management.
