DEFINITION

Classification: 508/356

The nitrogen is attached directly or indirectly to -C(=X)-, wherein X is chalcogen, by nonionic bonding (e.g., amides, aminocarboxylic acids, etc.):

(under subclass 355) Compositions wherein-C(=X)-, wherein X is chalcogen (i.e., oxygen, sulfur, selenium or tellurium), is attached directly or indirectly to the nitrogen of the organic nitrogen compound by nonionic bonding.
