DEFINITION

Classification: 504/255

Nitrogen, other than as nitro or nitroso, or -C(=X)-, wherein X is chalcogen, bonded directly to ring carbon of the six-membered hetero ring:

(under subclass 254) Compositions in which nitrogen, other than as nitro or nitroso (-NO₂ or -NO), or -C(=X)- wherein X is chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is bonded directly to a ring carbon of the six-membered hetero ring.

(1) Note. A nitro or nitroso group may be bonded directly to a ring carbon of the six-membered hetero ring, provided that a nitrogen which is not part of a nitro or nitroso group is also so attached.
