Carbamate

In organic chemistry, a carbamate is a category of organic compounds with the general formulaR₂NC(O)OR and structure>N−C(=O)−O−, which are formally derived from carbamic acid (NH₂COOH). The term includes organic compounds (e.g., the esterethyl carbamate), formally obtained by replacing one or more of the hydrogen atoms by other organic functional groups; as well as salts with the carbamate anionH₂NCOO (e.g. ammonium carbamate).

Polymers whose repeat units are joined by carbamate like groups −NH−C(=O)−O− are an important family of plastics, the polyurethanes.
