Description

Cholesteryl Carbonate is a high-purity organic compound derived from cholesterol, serving as a versatile and critical intermediate in advanced material science and pharmaceutical research. Its unique steroidal structure and carbonate functional group make it an essential building block for creating liquid crystal displays (LCDs), drug delivery systems, and specialized polymers. This compound is particularly valuable for R&D chemists and production engineers in the pharmaceutical, electronics, and specialty chemical industries seeking to develop innovative materials with specific optical or biocompatible properties.

Application

• Liquid Crystal Displays (LCDs): A key chiral dopant and intermediate in the synthesis of ferroelectric and cholesteric liquid crystals for high-performance displays and optical devices.
• Pharmaceutical Intermediates: Used in the research and development of steroidal drugs, prodrugs, and targeted drug delivery systems due to its biocompatibility and derivatization potential.
• Biomaterials & Polymers: Serves as a monomer or modifying agent for synthesizing specialty polymers with enhanced biocompatibility for medical implants and controlled-release matrices.
• Cosmetic & Personal Care: Employed in the formulation of high-end skincare products, acting as a stabilizer and delivery agent for active ingredients.
• Research & Development: A crucial standard and reagent in academic and industrial laboratories for studying membrane biophysics, lipid bilayers, and sterol chemistry.
• Chemical Synthesis: Functions as a protected form of cholesterol or a versatile starting material for further organic synthesis in complex molecule construction.

Quality Control

Our Cholesteryl Carbonate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, IR for identification, and loss on drying for moisture content. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support customer audits and can provide material to meet various research and cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
