Uses

1,3-Dimethylurea is used for synthesis of caffeine, theophylline, pharmaceuticals, textile aids, herbicides and others. In the textile processing industry 1,3-dimethylurea is used as intermediate for the production of formaldehyde-free easy-care finishing agents for textiles. The estimated world production of DMU is estimated to be less than 25,000 tons.
