Triphenylphosphine(TPP) is an important pharmaceutical intermediates, mainly used for the production of cephalosporins, rapamycin, clindamycin and other pharmaceutical raw materials, but also the production of liquid crystal materials.It is an important organic synthesis catalyst Ligand. Triphenylphosphine is a basic raw material for the rhodium phosphine complex catalyst and it is widely used in petrochemical industry at home and abroad. Triphenylphosphine is also used in the pharmaceutical industry, organic synthesis, analysis and other fields. Triphenylphosphine can be used as a catalyst for organic synthesis, as stabilizer in dye process, and as an analytical reagent. Therefore, triphenylphosphine has broad prospects for development in petrochemical industry, organic synthesis, dyes, pharmaceutical industry and analysis.
