Description

Coprostane is a saturated sterane derivative, specifically the 5β isomer of cholestane, which serves as a critical biochemical reference standard and research compound. Its defined structure makes it an essential tool for calibrating analytical instruments and validating methodologies in complex organic matrices. This high-purity compound is primarily utilized by research institutions, pharmaceutical R&D laboratories, and analytical service providers involved in steroid metabolism, geochemical biomarker studies, and method development.

Application

• Analytical Reference Standard: Used for the calibration of Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) systems in the analysis of sterols, stanols, and related compounds.
• Biochemical Research: Serves as a key intermediate or standard in studies of cholesterol metabolism, bile acid synthesis, and other sterol transformation pathways.
• Geochemical Biomarker: Employed as a standard in petroleum and environmental geochemistry to identify and quantify sterane biomarkers, aiding in oil-source rock correlation and maturity assessments.
• Pharmaceutical Development: Acts as a starting material or reference compound in the synthesis and purity assessment of novel steroid-based pharmaceuticals.
• Quality Control: Used in-house by chemical manufacturers to verify the purity and identity of related sterane products through comparative analysis.
