Description

Benzene, [2-(Trimethoxysilyl)Ethynyl]- is a specialized organosilicon compound featuring a unique combination of a benzene ring, an ethynyl linker, and a trimethoxysilyl functional group. This molecular architecture makes it a valuable silane coupling agent and a versatile building block for advanced material synthesis. It is primarily used in industries requiring surface modification, adhesion promotion, and the development of hybrid organic-inorganic polymers.

Application

• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, and metals to improve compatibility with organic polymers.
• Adhesion Promoter: Enhances the bond strength in coatings, sealants, and adhesive formulations, particularly on difficult-to-bond substrates.
• Precursor for Hybrid Materials: Serves as a key monomer in sol-gel processes for creating advanced ceramics, nanocomposites, and protective coatings.
• Pharmaceutical Intermediates: Employed in the synthesis of complex molecules and active pharmaceutical ingredients (APIs) requiring silicon-containing motifs.
• Crosslinking Agent: Facilitates the formation of stable, three-dimensional networks in silicone-based resins and elastomers.
• Research & Development: A critical reagent in academic and industrial R&D for exploring new materials in electronics, optics, and nanotechnology.

Quality Control

Our production of Benzene, [2-(Trimethoxysilyl)Ethynyl]- adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. Comprehensive Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided 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 place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
