1,3-Diphenylurea Explained

1,3-Diphenylurea is a phenylurea-type compound with the formula (PhNH)2CO (Ph = C6H5). It is a colorless solid that is prepared by transamidation of urea with aniline.

DPU is a cytokinin, a type of plant hormone that induces flower development. The cytokinin effect of DPU is relatively low, but other more potent phenylurea-type cytokinins have been reported.[1]

It was detected in coconut milk.[2]
