Description

(2-Bromoethoxy)Trimethylsilane is a versatile organosilicon reagent featuring a bromoethoxy functional group protected by a trimethylsilyl moiety. This compound is a critical building block in organic synthesis, valued for its role as a protected synthon for introducing ethylene oxide units and as a precursor to various functionalized silanes. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring ethylene glycol or polyether side chains.
• Polymer & Material Science: Used as a monomer or cross-linking agent in the production of specialty silicones and functional polymers.
• Surface Modification: Acts as a silylating agent to modify the surface properties of silica, glass, and other inorganic materials.
• Liquid Crystal & OLED Materials: Serves as a precursor in the synthesis of advanced organic electronic materials.
• Agrochemical Synthesis: Employed in the manufacture of herbicides, fungicides, and plant growth regulators.
• Protecting Group Chemistry: The trimethylsilyl group protects the alcohol functionality during multi-step synthetic sequences.

Quality Control

Our (2-Bromoethoxy)Trimethylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

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