DEFINITION

Classification: 504/210

Acyclic urea or thiourea bonded directly to ring carbon of the hetero ring (i.e., HNH-C(=X)-NH-, wherein X is sulfur or oxygen and substitution may be made for hydrogen only):

(under subclass 209) Compositions in which a HNH-C(=X)-NH- group, wherein X is sulfur or oxygen and substitution may be made for hydrogen only, is bonded directly to a ring carbon of the hetero ring.

(1) Note. Isoureas, isothioureas, pseudoureas, and pseudothioureas are not provided for in this subclass.

(2) Note. An example of a compound provided for herein is:
