N,n-dimethylurea

CAS: 598-94-7

Overview

N,N-Dimethylurea (CAS 598-94-7 ), also recognized commercially as 1,1-dimethylurea and asym-Dimethylurea, is a substituted urea derivative used across pharmaceutical synthesis, agrochemical production, and polymer chemistry.

It functions primarily as a solvent, reaction intermediate, and plasticizing agent in industrial formulations. In pharmaceutical and biotechnology manufacturing, it serves as a solvent and carrier in synthesis routes.

This compound is preferred where standard urea would introduce unwanted reactivity. Agrochemical formulators use it as a building block in the production of herbicides and plant growth regulators, particularly within the phenylurea class.

In polymer and resin systems, it acts as a plasticizer and softener, improving flexibility and processability in certain thermoset formulations. It also finds use in buffering and pH-control applications.

These applications are common within biological media and research-grade formulations. The product is supplied as a white crystalline solid or powder, ensuring ease of handling during the manufacturing process.

Technical and research grades are the most commonly available, with purity levels typically ranging from 98% to 99%+ for synthesis and laboratory applications. This ensures high performance in sensitive chemical reactions.

Packaging options generally range from small quantities for R&D use to bulk quantities for industrial procurement. This flexibility allows for seamless integration into both pilot-scale and full-scale production lines.
