Description

(2-[(Chlorocarbonyl)Oxy]Ethyl)Trimethylsilane is a specialized organosilicon reagent featuring a reactive chloroformate ester group linked to a trimethylsilyl-protected ethanol moiety. This compound matters as a versatile building block for introducing silyl-protected functional groups and for synthesizing complex molecules in a controlled manner. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for applications such as polymer modification and the synthesis of silicon-containing active ingredients.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing silyl-protected alcohol functionalities or as a coupling agent.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for modifying silicone polymers and creating specialty coatings with tailored properties.
• Agrochemical Synthesis: Acts as a key reagent in the production of silicon-based pesticides, herbicides, and plant growth regulators.
• Surface Modification: Employed to functionalize silica surfaces and other inorganic materials to alter their hydrophobicity or reactivity.
• Organic Synthesis Reagent: Utilized as a protecting group for alcohols or as a precursor for more complex organosilicon compounds in fine chemical synthesis.
• Adhesive & Sealant Formulations: Incorporated as an additive to enhance the curing characteristics and adhesion properties of silicone-based systems.

Quality Control

Our (2-[(Chlorocarbonyl)Oxy]Ethyl)Trimethylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and impurity profiling, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results 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 place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. This material is hygroscopic (moisture-sensitive) and reacts with strong acids and bases; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain stability.
