Description

General description

Diphenyl phosphoryl chloride is a diaryl phosphoryl derivative. It is formed during the preparation of monophenyl phosphoryl chloride via reaction of phenol and phosphorus oxychloride.

Application

Diphenyl phosphoryl chloride may be used:
• in the preparation of guanosine-adenosine-5′,5′-triphosphate, guanosine-cytidine-5′,5′-triphosphate, guanosine-uridine-5′,5′-triphosphate, diguanosine-5′,5′-diphosphate and diguanosine-5′,5′-triphosphate
• as phosphorylating agent for the synthesis of 2-deoxy-D-galactose-3 and -6 phosphoric acids
• in the synthesis of diaryl phosphoryl derivatives of alkylene dithiophosphates
