Dimethylene triurea (DMTU) is the organic compound with the formula (H₂NC(O)NHCH₂NH)₂CO. It is a white water-soluble solid. The compound is formed by the condensation of formaldehyde with urea. Both branched and linear isomers exist.

Applications

DMTU is an intermediate in the production of urea-formaldehyde resins.^[1]

Together with methylene diurea, DMTU is a component of some controlled-release fertilizers.^[2]
