Is Diphenylphosphine supplied neat or as a solution?

Both forms exist. Neat Diphenylphosphine and a stated concentration in hexane or another solvent are not interchangeable for dosing or transport. Specify CAS 829-85-6, active concentration, solvent, required quantity and whether the process can accept the solvent.

Which controls matter when purchasing Diphenylphosphine?

Agree active Diphenylphosphine assay, total phosphorus basis where used, Diphenylphosphine Oxide and other phosphorus impurities, water, color and the analytical method. Because the material is air-sensitive, also confirm inert-gas filling, compatible packaging and a low oxide or degradation limit.

What is Diphenylphosphine used for?

Diphenylphosphine is evaluated as a reactive organophosphorus intermediate for ligands, phosphine reagents and related synthesis where the PH functionality is required. The downstream reaction, solvent and air-free handling capability should be stated before grade selection.

How should Diphenylphosphine be stored and handled?

Keep in tightly sealed containers under inert gas in a cool, well-ventilated area away from air, oxygen, heat, sparks, oxidizers and incompatible halogenated materials. Use inerted transfer equipment, follow the current safety information, and maintain spill and fire controls appropriate for an air-sensitive phosphine.

What are the key physical properties of Diphenylphosphine?

Diphenylphosphine is a colorless liquid with molecular formula C12H11P, molar mass about 186.19 g/mol, density about 1.07 g/mL at 25 C and boiling point around 280 C. Its melting point is near -14.5 C, and it is very easily oxidized in air.

Diphenylphosphine CAS 829-85-6

Diphenylphosphine, also known as diphenylphosphane, is a secondary phosphine identified by CAS 829-85-6. It may be evaluated as a reactive intermediate for organophosphorus synthesis when the downstream reaction and handling requirements are defined. For an RFQ, state the downstream reaction, required specification, quantity, packaging and destination.
