Description

Silane, [[(5Alpha,11Beta)-Androsta-2,16-Diene-11,17-Diyl]Bis(Oxy)]Bis[ Trimethyl- is a specialized organosilicon derivative of a steroidal diene, designed for advanced chemical synthesis and material science applications. This compound is valued for its unique molecular architecture, which combines a reactive silane moiety with a complex steroid backbone, enabling precise surface modification and functionalization. It serves as a critical intermediate for researchers and manufacturers in the pharmaceutical, advanced polymer, and specialty chemical sectors seeking to develop novel materials with tailored properties.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel steroid-based active pharmaceutical ingredients (APIs) and prodrugs.
• Surface Modification Agent: Used to functionalize inorganic surfaces (e.g., silica, glass, metals) with organic steroid layers for biomedical devices and chromatography media.
• Advanced Polymer Synthesis: Serves as a specialized monomer or cross-linking agent for creating silicone-based polymers with unique steroidal side chains for controlled release or biomimetic materials.
• Research & Development: Essential reagent in academic and industrial R&D for exploring new organosilicon chemistry, catalysis, and material properties.
• Liquid Crystal & OLED Materials: Potential precursor for developing steroidal components in liquid crystal displays (LCDs) or organic light-emitting diodes (OLEDs) due to its rigid molecular structure.
• Chiral Stationary Phases: Can be immobilized on silica gel to create chiral stationary phases for the enantiomeric separation of complex molecules in analytical and preparative chromatography.

Quality Control

Our production of Silane, [[(5Alpha,11Beta)-Androsta-2,16-Diene-11,17-Diyl]Bis(Oxy)]Bis[ Trimethyl- adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and industrial use. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, supporting compliance with internal quality standards and customer-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
