NHNHCO
NHNHCO is a chemical formula that represents a molecule. This particular formula can be interpreted in a few ways depending on the context, but it most commonly refers to a derivative of hydrazine and a carbonyl group. One possible structure represented by NHNHCO is a carbazate derivative. Carbazates are organic compounds containing the functional group R-O-CO-NH-NH2. In the context of NHNHCO, R would be hydrogen, leading to hydrazinocarboxylic acid, also known as carbazic acid. Carbazic acid is a simple organic acid with the formula NH2NHCOOH. It is a derivative of hydrazine where one hydrogen atom on a nitrogen is replaced by a carboxyl group.
Another interpretation of NHNHCO could be related to isocyanic acid tautomers or their derivatives. Isocyanic acid
