Description

Silane, [(3Alpha,5Beta,11Alpha,17Beta)-Androstane-3,11,17-Triyltris(Ox Y)Tris[Trimethyl- is a highly specialized organosilicon derivative of the androstane steroid backbone, designed for advanced chemical synthesis and material science applications. This compound's core value lies in its unique molecular architecture, which combines a rigid steroid core with reactive trimethylsiloxy groups, enabling precise surface modification and the creation of novel hybrid materials. It is primarily needed by research and development teams in the pharmaceutical, specialty chemical, and advanced materials sectors for applications ranging from drug discovery to the development of functionalized surfaces and polymers.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel steroid-based drug candidates and active pharmaceutical ingredients (APIs).
• Surface Modification Agent: Used to functionalize inorganic surfaces (e.g., silica, glass, metals) with organic steroid moieties for biomedical devices, chromatography media, and sensors.
• Polymer Science: Acts as a monomer or cross-linking agent in the development of specialty silicone polymers and hybrid organic-inorganic materials with tailored properties.
• Chemical Research: Employed in academic and industrial R&D for exploring new organosilicon chemistry, catalysis, and material properties.
• Liquid Crystal & Advanced Materials: A potential precursor for creating mesogenic (liquid crystal) compounds and other advanced functional materials due to its rigid, anisotropic structure.
