Phenyl phosphorodiamidate is an organophosphorus compound with the formula C₆H₅OP(O)(NH₂)₂. A white solid, it is used as an inhibitor of urease,^[1] an enzyme that accelerates the hydrolysis of urea. In this way, phenyl phosphorodiamidate enhances the effectiveness of urea-based fertilizers. It is a component of the technology of controlled release fertilizers.^[2]

In terms of its molecular structure, phenyl phosphorodiamidate is a tetrahedral molecule structurally related to urea, hence its inhibitory function. It is a derivative of phosphoryl chloride.
