Description

5-Cholesten-3,26-Diol Di[3,5-Dinitrobenzoate]- CAS NO 103442-67-7 is a high-purity, sterol-derived chemical intermediate, specifically a dinitrobenzoate ester derivative of a cholestane diol. This compound is valued for its role as a critical synthetic precursor and analytical standard in advanced organic chemistry and life science research. It is primarily needed by pharmaceutical R&D laboratories, fine chemical manufacturers, and academic institutions engaged in steroid chemistry, metabolic pathway studies, and the development of novel bioactive molecules.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the multi-step synthesis of complex steroid-based drug candidates and novel therapeutic agents.
• Biochemical Research: Used as a reference standard or probe in metabolic studies, enzyme inhibition assays, and investigations into cholesterol biosynthesis pathways.
• Fine Chemical Synthesis: Acts as a specialized precursor for creating custom sterol derivatives with modified functional groups for material science or catalysis applications.
• Analytical Chemistry: Employed as a high-purity calibrant or internal standard in chromatographic (HPLC, GC) and spectroscopic analyses for quality control and method development.
