Description

Dihydrocholesterol is a saturated sterol derivative, also known as cholestanol, which serves as a key intermediate and reference standard in advanced biochemical synthesis and research. Its fully hydrogenated structure provides a stable, non-oxidizable core for developing high-value pharmaceutical precursors and calibrating analytical methods in lipidomics. This compound is essential for manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and life science sectors requiring precise sterol analogs for metabolic studies, drug development, and quality control processes.

Application

• Pharmaceutical Intermediate: A critical starting material for the synthesis of specialized steroid-based active pharmaceutical ingredients (APIs) and hormone analogs.
• Biochemical Research & Reference Standard: Used as a high-purity internal standard in gas chromatography (GC) and liquid chromatography (LC) for the accurate quantification of sterols and related metabolites in biological samples.
• Nutraceutical Development: Employed in research for formulating and studying novel lipid-based supplements and functional food ingredients.
• Diagnostic Reagent Manufacturing: A component in the production of calibration kits and reagents for clinical diagnostics, particularly in cholesterol and lipid panel testing.
• Material Science: Investigated for its potential in creating specialized lipid membranes and vesicles for drug delivery systems.
• Academic & Industrial R&D: Serves as a model compound in studies of sterol metabolism, membrane biophysics, and enzymatic pathways.

Quality Control

Our Dihydrocholesterol is produced under a strict quality management system to ensure batch-to-batch consistency and high purity suitable for research and industrial applications. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substance profiling, to meet stringent in-house specifications. A Certificate of Analysis (COA) detailing identity, purity, and physical characteristics is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged exposure to air should be avoided. Keep the container sealed after each use to maintain product integrity.
