Description

Dihydrocholesterol is a saturated sterol derivative, also known as cholestanol, which serves as a key intermediate and reference standard in advanced biochemical research and synthesis. Its stable, hydrogenated structure makes it a valuable building block for producing other steroidal compounds and for use in analytical applications where a non-oxidizable cholesterol analog is required. This high-purity material is essential for pharmaceutical R&D laboratories, academic institutions, and fine chemical manufacturers focused on lipid metabolism studies, diagnostic reagent development, and the synthesis of specialized bioactive molecules.

Application

• Pharmaceutical Intermediate: A crucial starting material or intermediate in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a stable internal standard or reference compound in lipidomics, metabolomics, and cholesterol pathway studies.
• Diagnostic Reagents: Employed in the formulation of calibration standards and controls for clinical diagnostic kits measuring cholesterol and related sterols.
• Nutraceutical Research: Investigated for its potential biological activity and role in lipid metabolism as a cholesterol derivative.
• Material Science: Can serve as a precursor or additive in the development of specialized liquid crystals or other advanced organic materials.
