What is Sodium Tetraphenylboron？

Sodium Tetraphenylboron is an organoboron compound appearing as a white crystalline powder. It is soluble in water, methanol, and acetone, but insoluble in non-polar solvents. The compound is widely used as a precipitating agent and analytical reagent in chemical analysis and organic synthesis due to its ability to form insoluble salts with large cations.

Application：

Precipitating agent:

It reacts with certain metal and ammonium ions, such as potassium, to form insoluble precipitates, which can be used for their detection and quantitative determination.

Organic synthesis:

It serves as a source of phenyl groups in palladium-catalyzed reactions to create new carbon-carbon bonds.

Ion exchange:

It can be used to create stable, crystalline N-acylammonium salts from other ions.

Protecting agent:

It is used to protect amino acids and in the preparation of N-acylammonium salts.

Safety Profile:

Sodium Tetraphenylboron may cause skin and eye irritation. Inhalation of dust may cause respiratory irritation. Use appropriate personal protective equipment including gloves, safety glasses, and dust mask when handling. Avoid breathing dust and ensure adequate ventilation. The substance may be harmful to aquatic life. For detailed safety information, always consult the full Safety Data Sheet (SDS).

Storage Requirements:

Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly sealed and protected from moisture. Maintain storage temperature between 15-25°C. Relative humidity below 50% recommended. Handle under dry conditions when opening containers.

Transport & Packaging:

Sodium Tetraphenylboron is packaged in double-sealed aluminum bags with desiccant (1 kg or 5 kg net weight per bag), placed in sturdy outer containers. Transport as non-hazardous material under normal conditions. Ensure containers are properly sealed and protected from moisture during transportation. Store away from incompatible materials.
