Description

Silane, [(2E)-4-(2,2-Dimethyl-1,3-Dioxolan-4-Yl)-2-Butenyl]Trimethyl- (9Ci) CAS NO 792966-27-9 is a specialized organosilicon compound featuring a protected diol moiety and a reactive trimethylsilyl group. This unique bifunctional structure makes it a valuable versatile intermediate for synthesizing complex molecules in advanced material science and fine chemical production. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing sophisticated molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring silicon-containing or protected diol functionalities.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where its silane group aids in stability and bioavailability.
• Polymer Modification: Serves as a functional monomer or cross-linking agent for creating specialty silicones and hybrid organic-inorganic polymers with tailored properties.
• Surface Functionalization Agent: Employed to modify material surfaces (e.g., silica, metals) to introduce specific chemical groups for improved adhesion or compatibility.
• Chiral Synthesis: Utilized in asymmetric synthesis due to the chiral center present in the dioxolane ring structure.
• Liquid Crystal & OLED Material Precursor: Acts as a starting material for synthesizing components used in display and lighting technologies.
• Protecting Group Chemistry: The acetonide (dioxolane) group effectively protects diols during multi-step synthetic sequences.
