Description

Silane, Trimethyl(Oxiranylethynyl)- (9Ci) is a specialized organosilicon compound featuring a unique molecular architecture that combines a silane core with an oxiranyl (epoxide) and an ethynyl (alkyne) functional group. This structure makes it a highly valuable multifunctional chemical building block for advanced material synthesis. It is primarily sought after by R&D and production teams in the polymer, adhesive, and specialty coatings industries for creating novel cross-linked networks with tailored properties.

Application

• Advanced Polymer Modification: Acts as a reactive cross-linking agent or chain extender in epoxy, silicone, and polyurethane systems to enhance thermal stability and mechanical strength.
• Surface Coupling Agent: Used to functionalize inorganic surfaces (glass, silica, metals) for improved adhesion in composite materials and coatings.
• Specialty Adhesives & Sealants: A key intermediate for formulating high-performance, chemically resistant adhesives and sealants.
• Photoresist and Electronic Materials: Serves as a precursor in the development of photoresists and dielectric materials for the microelectronics industry.
• Hydrophobic Coatings: Employed in the synthesis of water-repellent and anti-corrosion surface treatments.
• Organic Synthesis Intermediate: A versatile building block in pharmaceutical and agrochemical research for constructing complex molecular frameworks.

Quality Control

Our production of Silane, Trimethyl(Oxiranylethynyl)- adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including GC, NMR, and FTIR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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.
