4. Applications

• Organic Synthesis Intermediate: Used in the preparation of acylsilane derivatives, silicon-containing ketones, and pharmaceutical intermediates.
• Cross-Coupling Reactions: Employed in Suzuki-Miyaura, Hiyama, and other transition-metal-catalyzed coupling reactions.
• Material Science: Precursor for functional silicones, surface modifiers, and adhesion promoters.
• Research & Development: Exclusive for laboratory R&D purposes; not for pharmaceutical or industrial production without further validation.

5. Handling & Storage

• Storage Conditions: Store in a cool, dry, well-ventilated area (2–8°C recommended for long-term storage). Keep container tightly sealed under inert gas (nitrogen/argon) to prevent moisture and air exposure.
• Handling Precautions: Avoid inhalation, skin contact, and eye contact. Use in a fume hood with appropriate PPE (nitrile gloves, safety goggles, lab coat).
• Shelf Life: 12 months under recommended storage conditions (unopened).

6. Delivery

• Delivery: Shipped as non-hazardous goods (dry ice for temperature control if required).
