white crystalline powder | [Uses]
Diphenyl Phosphate is an organophosphate diester and metabolite of the flame retardant Triphenyl Phosphate (T808990) and also a metabolite of 2-Ethylhexyl diphenyl phosphate. | [Definition]
ChEBI: Diphenyl phosphate is an aryl phosphate. | [Purification Methods]
Crystallise it from CHCl3/pet ether. [Cherbuliez in Organo Phosphorus Compounds (Kosolapoff & Maier eds) Wiley Vol 6 pp 211-577 1973, Beilstein 6 IV 714.] | [Toxics Screening Level]
The initial threshold screening level (ITSL) for diphenyl phosphoric acid is 0.1 μg/m3 based on annual averaging time. | [References]
