DEFINITION

Classification: 508/335

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

(under subclass 334) Compositions wherein-C(=X)-, wherein X is chalcogen (i.e., oxygen, sulfur, selenium, or tellurium), is attached directly or indirectly to the nitrogen by nonionic bonding.
