C07C237/46 - CPC Classification

Classification description:

Carboxylic acid amides, the carbon skeleton of the acid part being further substituted by amino groups having the carbon atom of at least one of the carboxamide groups bound to a carbon atom of a non-condensed six-membered aromatic ring of the carbon skeleton having carbon atoms of carboxamide groups, amino groups and at least three atoms of bromine or iodine, bound to carbon atoms of the same non-condensed six-membered aromatic ring
