karbamamiidurea

Karbamamiidurea is a chemical compound described in chemical literature as a carbamamido derivative of urea. The name indicates a molecule that combines a carbamamide moiety with the urea core, resulting in multiple amide groups and high polarity.

Reported structures vary, but the motif commonly involves two ureido units linked to form a diurea framework. The compound is expected to be highly polar, with significant hydrogen-bonding potential, and likely non-volatile. It is typically a solid at room temperature with limited commercial availability.

Preparations cited in studies typically involve condensation of urea with carbamoylating reagents such as isocyanates or carbamoyl chlorides, or sequential coupling of ureido fragments under heat or catalysis. Purification often requires crystallization or chromatography.

Karbamamiidurea has mainly appeared in academic contexts as a synthetic intermediate, a model compound for hydrogen-bonding networks, or in discussions of polymerizable ureide motifs. It is not known to have widespread industrial use or natural occurrence.

As with many amide-rich organic compounds, handling should follow standard laboratory safety practices. Avoid inhalation or direct contact; use appropriate personal protective equipment; store in a labeled, tightly closed container.

Information about karbamamiidurea is drawn from a limited set of chemical studies and reviews.
