1,3-Diphenylurea is a phenylurea-type cytokinin, a type of plant hormone that induces flower development.

Folke Skoog discovered the effects of cytokinins using coconut milk in the 1940s at the University of Wisconsin–Madison. 1,3-Diphenylurea is a compound that has been thereafter identified in coconut milk.^[1]

The cytokinin effect of DPU is considered low as compared to that of adenine derivatives such as zeatin. Nevertheless, there have been subsequent discoveries of other more potent phenylurea-type cytokinins.^[2]
