Description

14,15,17,18-Tetrakis[(Trimethylsilyl)Oxy]Octadecanoic Acid Methyl Ester is a specialized organosilicon derivative of a fatty acid methyl ester, characterized by its four trimethylsilyl-protected hydroxyl groups. This compound is valued for its role as a key synthetic intermediate and protecting group reagent in advanced organic synthesis. It is primarily utilized by research and development chemists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of complex drug candidates, particularly those requiring selective hydroxyl group protection.
• Agrochemical Research: Used in the development of novel active ingredients where the silyl ether groups provide stability during synthesis.
• Advanced Material Synthesis: Acts as a precursor or modifying agent in the creation of specialty polymers and surface-active materials.
• Organic Synthesis Reagent: Functions as a protected form of a polyhydroxy stearate for controlled reactions in multi-step synthetic pathways.
• Biochemical Research: Employed in lipidomics and metabolic studies as a derivatization standard for gas chromatography-mass spectrometry (GC-MS) analysis.
• Chemical Reference Standard: Used for analytical method development and validation in quality control laboratories.

Quality Control

Our 14,15,17,18-Tetrakis[(Trimethylsilyl)Oxy]Octadecanoic Acid Methyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent identity. Certificates of Analysis (COA) detailing purity, impurities, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

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