Description

Epicholesterol CAS NO 474-77-1 is a specific stereoisomer of cholesterol, a fundamental sterol in biological systems. This compound is of significant value as a high-purity reference standard and a critical intermediate in pharmaceutical research and fine chemical synthesis. It is primarily needed by research institutions and manufacturers in the pharmaceutical, biotechnology, and life science sectors for analytical method development, metabolic studies, and the production of specialized steroid derivatives.

Application

• Pharmaceutical Reference Standard: Used for the calibration of analytical instruments (HPLC, GC-MS) and for quality control in the analysis of sterol-based drugs and biological samples.
• Biochemical Research: Serves as a key intermediate in studies of cholesterol metabolism, membrane biophysics, and the synthesis of labeled compounds for tracer experiments.
• Fine Chemical Synthesis: Acts as a chiral building block for the synthesis of more complex steroid hormones, vitamin D analogs, and other bioactive molecules.
• Academic Research: Utilized in universities and research labs for investigating stereospecific enzymatic reactions and the biological activity of different cholesterol isomers.
