Tributyl Phosphine(CAS: 998-40-3)

Tributyl phosphine, with the CAS number 998-40-3, is an organophosphorus compound with the chemical formula C12H27P. It is a colorless liquid with a mild odor and is commonly used as a phosphine donor in chemical reactions. Tributyl phosphine is known for its stability under normal conditions and its ability to act as a reducing agent in various synthetic processes.

Tributyl phosphine is widely utilized in pharmaceuticals, organic synthesis, and industrial chemistry. It serves as a key reagent in coupling reactions, catalytic processes, and as a ligand in transition metal complexes. Additionally, it finds applications in the production of pesticides, flame retardants, and specialty chemicals. Its role in research settings is significant for developing new materials and compounds.

Tributyl phosphine is considered hazardous and requires careful handling. It can cause skin and eye irritation, and inhalation may lead to respiratory issues. Safety standards recommend using appropriate personal protective equipment (PPE) such as gloves, goggles, and a fume hood. It is also flammable, so storage and use should follow strict safety protocols to prevent accidents.

Tributyl phosphine should be stored in a cool, dry, and well-ventilated area, away from heat and direct light. It is typically kept in sealed, airtight containers made of materials compatible with its chemical properties, such as polyethylene or glass. Due to its flammability, storage should be in a fire-resistant cabinet. Maintain storage conditions below 25°C and ensure humidity levels are low to prevent degradation.
