Description

Cerevisterol is a naturally occurring sterol compound, structurally related to ergosterol, which serves as a key intermediate and reference standard in biochemical research. Its significance lies in its role as a biosynthetic precursor and its utility in studying sterol metabolism and membrane function in fungi and other organisms. This high-purity compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors, particularly those focused on antifungal agent development, metabolic pathway analysis, and the production of reference materials.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and assay development of antifungal drugs and related sterol-based pharmaceuticals.
• Biochemical Research: Serves as a critical intermediate and probe in studies of fungal ergosterol biosynthesis pathways, aiding in the discovery of novel antifungal targets.
• Life Science Reagents: Employed in the formulation of specialized cell culture media and as a component in biochemical assays investigating membrane structure and function.
• Academic & Industrial R&D: Utilized as a building block or starting material in synthetic chemistry for the preparation of more complex sterol derivatives with potential bioactivity.
• Analytical Chemistry: Functions as a high-purity calibration standard in chromatographic (HPLC, GC) and spectroscopic analyses for accurate quantification of sterols in complex matrices.
