DEFINITION

Classification: 564/213

(under subclass 212) Compounds wherein the amino nitrogen containing residue contains a nitro group and an ether, or contains a nitro group an a hydroxyl, which hydroxyl is bonded directly to carbon and wherein the H of the -OH may be replaced by a substituted or unsubstituted ammonium or a Group IA or IIA light metal.
