DEFINITION

Classification: 508/196

With nitrogen heterocycle compound (e.g., thiadiazoles, etc.):

(under subclass 195) Compositions which contain, in addition to the boron component, a nitrogen heterocycle compound.

(1) Note. A nitrogen heterocycle is a ring whose ring members are carbon and at least one hetero atom selected from nitrogen and chalcogen (i.e., oxygen, sulfur, selenium, or tellurium). In this subclass, the heterocycle must contain ring nitrogen.
