Description

1,1-Dimethylsilacyclohexan-4-One CAS NO 18276-42-1 is a specialized organosilicon compound featuring a unique cyclic structure that combines a silacyclohexane ring with a ketone functional group. This molecular architecture makes it a valuable intermediate for advanced material synthesis, particularly in the development of novel silicone polymers and functionalized silanes. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular frameworks and modifying material surfaces.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for introducing silicon into drug candidates (silicon-switch strategy).
• Agrochemical Synthesis: Used in the research and development of new-generation pesticides and herbicides, where its structure can contribute to enhanced biological activity or environmental stability.
• Specialty Polymer & Resin Modifier: Acts as a monomer or cross-linking agent for creating silicone-based polymers with tailored thermal, mechanical, or surface properties.
• Surface Functionalization Agent: Employed to modify inorganic surfaces (e.g., silica, metals) to impart specific organic functionalities for coatings, adhesives, or composite materials.
• Ligand & Catalyst Development: Utilized in organometallic chemistry and catalysis research to develop new silicon-containing ligands for transition metal complexes.
• Material Science Research: A precursor for developing silicon-carbon hybrid materials, including sol-gel ceramics and advanced nanocomposites.
