Description

5,7,22-Cholestatrien-3Beta-Ol CAS NO 19633-95-5 is a high-purity sterol derivative, specifically a cholestatrienol, that serves as a critical intermediate and reference standard in advanced biochemical research and pharmaceutical development. Its unique conjugated triene structure makes it valuable for studying cholesterol biosynthesis pathways, membrane biophysics, and as a precursor for synthesizing more complex steroid-based compounds. This compound is essential for researchers and manufacturers in the pharmaceutical, life sciences, and fine chemical sectors who require well-characterized, high-quality sterols for analytical, diagnostic, and synthetic applications.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel steroid drugs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard and probe in studies of cholesterol metabolism, lipid raft formation, and sterol-protein interactions.
• Analytical Standard: Serves as a high-purity calibration standard in chromatographic (HPLC, GC) and spectroscopic analyses for quality control laboratories.
• Nutraceutical Research: Investigated for potential applications in the study of plant sterols and their derivatives in health and wellness products.
• Material Science: Explored as a precursor for creating specialized liquid crystals or organic semiconductors due to its rigid, planar structure.

Quality Control

Our 5,7,22-Cholestatrien-3Beta-Ol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, IR, MS) for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and handled under conditions that minimize exposure to ambient light and humidity to maintain stability and purity.
