Trimethoxysilane | CAS No. 2487-90-3

Q: What is Trimethoxysilane (CAS: 2487-90-3)?

Trimethoxysilane (CAS: 2487-90-3) is a colorless, volatile liquid with the chemical formula (CH3O)3Si. It exhibits hydrophobic properties and is commonly used as a precursor for silicone-based materials. Trimethoxysilane reacts with water to form silanols and is known for its ability to modify surfaces in chemical reactions.

Q: What are the main uses of Trimethoxysilane (CAS: 2487-90-3)?

Trimethoxysilane (CAS: 2487-90-3) is widely used in the production of silicones, coatings, and adhesives. It serves as a coupling agent in pharmaceuticals to enhance drug delivery systems. Additionally, it finds applications in industrial manufacturing, research for surface functionalization, and as a component in electronic materials due to its chemical reactivity and stability.

Q: Is Trimethoxysilane (CAS: 2487-90-3) safe?

Trimethoxysilane (CAS: 2487-90-3) is generally considered safe when handled properly. It may cause skin and eye irritation, so protective measures like gloves and ventilation are recommended. Safety standards include compliance with OSHA and REACH regulations. While low toxicity is reported, prolonged exposure should be avoided to ensure safety.

Q: How should Trimethoxysilane (CAS: 2487-90-3) be stored?

Trimethoxysilane (CAS: 2487-90-3) should be stored in a cool, dry, and well-ventilated area, away from moisture and light. Use sealed containers made of glass or HDPE to maintain stability. Keep it at temperatures below 25°C and avoid humidity to prevent hydrolysis. Store in a fire-safe location to ensure chemical safety.
