Description

(Dimethylamino)Fluorodimethylsilane is a highly reactive organosilicon compound that serves as a versatile building block in advanced material synthesis. Its value lies in its bifunctional nature, combining a reactive silicon-fluorine bond with a basic dimethylamino group, enabling precise surface modification and polymer functionalization. This chemical is essential for manufacturers in the semiconductor, specialty polymer, and pharmaceutical intermediate sectors seeking to enhance material properties and process efficiency.

Application

• Semiconductor Manufacturing: Used as a silylating agent and surface modifier in the production of low-k dielectric films and for passivating silicon wafer surfaces.
• Silicone & Polymer Chemistry: Acts as a key monomer or coupling agent in the synthesis of specialty silicones, fluorosilicones, and block copolymers.
• Surface Treatment & Coatings: Provides hydrophobic and oleophobic properties to glass, metals, and ceramics for advanced coating formulations.
• Pharmaceutical Intermediates: Serves as a protected synthon or reagent in the synthesis of complex molecules, leveraging its reactive silicon center.
• Adhesives & Sealants: Functions as an adhesion promoter and cross-linking agent in high-performance silicone-based formulations.
• Chemical Vapor Deposition (CVD): Employed as a precursor gas for depositing silicon-containing thin films on various substrates.

Quality Control

Our (Dimethylamino)Fluorodimethylsilane is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with each shipment. We adhere to relevant industry standards and can support requirements for REACH, TSCA, and other global regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its hygroscopic and highly volatile nature, containers must be kept sealed under an inert atmosphere (argon or nitrogen) and allowed to equilibrate to room temperature before opening to prevent moisture ingress and pressure buildup.
