Description

Butyldimethyl(Dimethylamino)Silane is a versatile organosilicon compound that serves as a key reagent and intermediate in advanced material synthesis. Its value lies in its bifunctional nature, combining a reactive dimethylamino group with a hydrolytically stable butyldimethylsilyl moiety, enabling precise surface modification and controlled chemical grafting. This product is essential for R&D and production teams in the semiconductor, specialty polymer, and pharmaceutical industries seeking to impart specific surface properties or create novel silicon-based architectures.

Application

• Surface Modification Agent: Used to functionalize silica, glass, and metal oxide surfaces for improved adhesion, hydrophobicity, or biocompatibility.
• Silicon Precursor in CVD/ALD: Acts as a volatile silicon source in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for thin-film coatings.
• Silylating Reagent: Employed in organic synthesis to protect hydroxyl groups or introduce the butyldimethylsilyl (BDMS) protecting group, which offers stability under various conditions.
• Crosslinking Agent: Facilitates the formation of silicone networks and elastomers, enhancing thermal and mechanical properties.
• Adhesion Promoter: Incorporated into primers and coatings to improve bonding between organic polymers and inorganic substrates.
• Pharmaceutical Intermediate: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs that incorporate silicon.

Quality Control

Our production of Butyldimethyl(Dimethylamino)Silane adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is analyzed via GC, NMR, and Karl Fischer titration to verify identity, potency, and moisture content. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support customers requiring material for GMP or other regulated applications with appropriate documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (nitrogen or argon) to prevent degradation. Keep away from heat, sparks, open flames, and strong oxidizers.
