Description

Cholesterol Hydrogen Phthalate is a high-purity chemical derivative formed by the esterification of cholesterol and phthalic acid. This compound is valued for its role as a critical intermediate and reference standard in advanced pharmaceutical research and analytical chemistry. It is primarily utilized by R&D laboratories, quality control departments, and manufacturers in the pharmaceutical, life sciences, and fine chemical sectors for method development and validation.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments and validation of testing methods in pharmacopeial compliance (e.g., USP, EP).
• Biochemical Research: Serves as a key intermediate or substrate in metabolic pathway studies and the synthesis of more complex sterol derivatives.
• Analytical Chemistry: Employed in High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC) as a standard for quantifying cholesterol and related sterols.
• Material Science: Investigated for its potential in creating specialized polymers or liquid crystals due to its sterol-based structure.
• Diagnostic Reagents: Can be used in the formulation of reagents and kits for clinical diagnostics and enzymatic assays.
