Diphenylphosphine (CAS No. 829-85-6) is a highly versatile organophosphorus compound with the molecular formula C12H11P. This air-sensitive, colorless to pale yellow liquid is widely used as a key intermediate in organic synthesis, catalysis, and ligand formation for transition metal complexes. Its reactive P-H bond enables facile functionalization, making it invaluable in pharmaceutical, agrochemical, and materials science research. Diphenylphosphine is particularly valued for its role in synthesizing phosphine ligands for asymmetric catalysis and as a precursor for flame retardants and photoinitiators. Packaged under inert gas to ensure stability, our ≥98% purity grade meets stringent analytical standards (GC, NMR) for demanding applications. Handle with care under inert atmosphere due to pyrophoric tendencies.

Diphenylphosphine serves as a crucial building block for phosphine ligands in homogeneous catalysis (e.g., cross-coupling reactions). It’s employed in the synthesis of chiral catalysts for asymmetric hydrogenation and as a precursor for flame-retardant additives in polymers. The compound also finds use in semiconductor manufacturing through deposition of phosphorus-containing thin films.
