DEFINITION

Classification: 514/183

Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., O, S, Se, or Te) or nitrogen as the only ring hetero atoms DOAI:

(under subclass 1) Subject matter which includes a compound containing a ring composed of carbon and at least one element from the group consisting of nitrogen, sulfur, selenium, tellurium and oxygen as DOAI.

(1) Note. Excluded herefrom are those carbon compounds wherein the only heterocyclic nucleus present is produced by salt formation between amino and acid groups, e.g., betaines, which are placed with the corresponding open chain compounds, particularly subclass 556.
