Description

(Methylthio)Silane CAS NO 16643-15-5 is a specialized organosilicon compound featuring a methylthio functional group, making it a valuable intermediate for surface modification and cross-linking reactions. Its primary value lies in its ability to act as a coupling agent and a precursor for introducing sulfur-containing functionalities into polymers and inorganic matrices. This product is essential for manufacturers in the advanced materials, specialty polymers, and coatings industries seeking to enhance adhesion, modify surface properties, or create novel hybrid materials.

Application

• As a key coupling agent and surface modifier for inorganic fillers (e.g., silica, glass) in composite materials.
• As a cross-linking agent and chain extender in the synthesis of specialty silicone polymers and rubbers.
• As a precursor for functional coatings to impart specific surface characteristics like hydrophobicity or chemical resistance.
• In the development of adhesion promoters for challenging substrates in the automotive and aerospace sectors.
• As an intermediate in the synthesis of more complex organosilicon compounds for pharmaceutical and agrochemical applications.
• For research and development in material science, particularly in creating novel hybrid organic-inorganic materials.

Quality Control

Our (Methylthio)Silane is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including gas chromatography (GC) and spectroscopic methods, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, away from heat sources and open flames. Recommended storage temperature is between 2°C and 8°C to minimize volatility and maintain stability. Keep container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent moisture ingress and degradation.
