Triphenylphosphine is a common organophosphorus compound with the molecular formula C18H15P. It appears as a white powder and is classified as an industrial-grade analytical reagent. Its core function is as a polymerization initiator and environmentally friendly catalyst, widely used in organic synthesis. This substance participates in electron transfer processes in chemical reactions by donating electron pairs from phosphorus atoms in its molecular structure, thereby lowering the activation energy and improving reaction efficiency.
Triphenylphosphine is formed by three phenyl groups (C6H5) covalently linked to one phosphorus atom, resulting in a stable molecular structure. Its CAS number is 603-35-0, conforming to national standards, with an effective component content of 99% and extremely low impurity content. Physically, it is a white powder and should be stored in a cool, dry place at room temperature in a sealed container to avoid deterioration due to contact with moisture or oxygen in the air. It is packaged in 25kg drums for convenient storage and transportation in industrial settings.
