Description

4-(Dihydroxymethylsilyl)Butyronitrile is a versatile organosilicon compound featuring both nitrile and silanol functional groups. This unique bifunctional structure makes it a valuable intermediate for synthesizing advanced silicone polymers and surface-modifying agents. It is particularly sought after by manufacturers in the silicone elastomer, adhesive, and specialty coating industries who require materials with tailored reactivity and performance characteristics.

Application

• Crosslinking Agent in the synthesis of specialty silicone resins and high-performance elastomers.
• Surface Modifier for inorganic fillers (e.g., silica, glass) to improve compatibility and dispersion in polymer matrices.
• Key Intermediate for producing silane coupling agents with nitrile-terminated organic chains.
• Adhesive Formulation component, contributing to enhanced adhesion on various substrates.
• Precursor for functionalized polysiloxanes used in release coatings and pressure-sensitive adhesives.
• Building Block in pharmaceutical and agrochemical research for introducing silyl groups.

Quality Control

Our production of 4-(Dihydroxymethylsilyl)Butyronitrile adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay and impurity profiling, to ensure consistency and high purity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
