Description

Silane, [[(3Beta,17Beta)-Androsta-5,15-Diene-3,16,17-Triyl]Tris(Oxy)]Tris[Trimethyl- is a specialized organosilicon derivative of a steroidal diene. This compound is significant for its role as a key synthetic intermediate in advanced pharmaceutical and fine chemical research, particularly in the development of novel steroid-based therapeutics. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, biotechnology, and advanced organic synthesis sectors.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of novel steroid-based drug candidates and active pharmaceutical ingredients (APIs).
• Advanced Organic Synthesis: Used in complex multi-step syntheses, including cross-coupling reactions and the introduction of silicon-protecting groups.
• Bioconjugation Research: Potential utility in creating steroidal probes or conjugates for biochemical and diagnostic applications.
• Material Science Precursor: Can serve as a functionalized precursor for creating specialized silicone-based polymers or surface modifiers with steroidal moieties.
• Academic & Industrial R&D: Employed in research programs focused on steroid chemistry, hormone analogs, and new chemical entity (NCE) discovery.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity and purity, with a focus on meeting the stringent requirements for pharmaceutical R&D and advanced synthesis. Certificates of Analysis (COA) detailing specific analytical results, including assay and impurity profiles, are available upon request.

Storage

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