Description

2-Cyanoethyltrimethylsilane is a versatile organosilicon compound featuring a reactive cyanoethyl group. This chemical matters for its role as a key silylating agent and synthetic intermediate, enabling the introduction of trimethylsilyl groups into complex molecules. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications ranging from protecting group chemistry to surface modification.

Application

• Pharmaceutical Intermediate: Used as a protecting agent for hydroxyl groups during the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Serves as a key building block in the production of certain herbicides, fungicides, and plant growth regulators.
• Surface Modification Agent: Employed to functionalize silica, glass, and other inorganic surfaces, altering their hydrophobicity and reactivity.
• Polymer & Resin Chemistry: Acts as a monomer or cross-linking agent in the synthesis of specialty silicones and high-performance polymers.
• Chemical Derivatization: Utilized in analytical chemistry to silylate compounds for Gas Chromatography (GC) and Mass Spectrometry (MS) analysis.
• Adhesive & Sealant Formulations: Incorporated as an adhesion promoter and moisture scavenger in silicone-based sealants and adhesives.

Quality Control

Our 2-Cyanoethyltrimethylsilane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee compliance with your specific application requirements.

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 after opening to prevent degradation by atmospheric moisture.
