Application
Diphenylphosphine oxide is commonly used in the preparation of triphenylphosphine oxide, alkyne addition, and Wittig Horner reaction reagents. The synthesis of diphenylphosphine derivatives involves the coupling of Ph2P (O) H with trifluoromethanesulfonic acid aryl ester, and the reduction of phosphine oxide to obtain diphenylarylphosphine, which is a commonly used chiral ligand.
Packing
Usually packed in 25kg/drum,and also can be do customized package.
