Description

Diphenyl-T-Butylsilanol CAS NO 93547-88-7 is a specialized organosilicon compound featuring a silanol group (-SiOH) protected by bulky organic substituents. This unique structure makes it a valuable intermediate and protecting group reagent in advanced synthetic chemistry, particularly for the controlled modification of sensitive molecules. It is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity, reliable building blocks for complex synthesis.

Application

• Pharmaceutical Intermediate: Serves as a key building block and protecting group in the synthesis of active pharmaceutical ingredients (APIs), especially for silicon-containing drug candidates.
• Agrochemical Synthesis: Used in the development and production of novel pesticides and herbicides where silicon incorporation can enhance stability or bioavailability.
• Advanced Material Precursor: Acts as a monomer or modifying agent in the synthesis of specialty silicones, siloxane polymers, and hybrid organic-inorganic materials.
• Cross-Coupling Reactions: Functions as a reagent in palladium-catalyzed cross-coupling reactions, such as Hiyama couplings, due to the reactivity of the silanol group.
• Surface Modification Agent: Employed to functionalize silica surfaces or other oxides, altering surface properties for specific industrial applications.
• Laboratory Research & Development: A versatile tool for academic and industrial R&D in organic and organometallic chemistry for exploring new synthetic pathways.

Quality Control

Our Diphenyl-T-Butylsilanol is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. Keep away from incompatible materials such as strong acids and bases.
