Description

3-Triethoxycholesterol is a synthetic cholesterol derivative where three ethoxy groups replace hydroxyl functionalities. This chemical modification enhances its solubility in organic solvents and alters its biological and material properties, making it a valuable intermediate for advanced research and synthesis. It is primarily utilized by pharmaceutical researchers, material scientists, and specialty chemical manufacturers developing novel drug delivery systems, liquid crystal materials, and other functional organic compounds.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel steroidal drugs and prodrugs, particularly for enhancing bioavailability.
• Liquid Crystal Research: Used as a chiral dopant or precursor in the development of advanced liquid crystal displays (LCDs) and optical materials.
• Biomimetic Material Science: Serves as a precursor for creating synthetic lipid membranes and vesicles for drug delivery and diagnostic applications.
• Chemical Synthesis: An important intermediate for further functionalization to create specialized surfactants, polymers, and other sterol-based compounds.
• Reference Standard: Employed as an analytical standard in quality control laboratories for method development and validation in pharmaceutical analysis.

Quality Control

Our 3-Triethoxycholesterol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 tightly sealed after each use to prevent degradation.
