DEFINITION

Classification: 508/295

With organic chalcogen or halogen compound:

(under subclass 293) Compositions which contain, in addition to the hetero ring containing component, an organic halogen compound or an organic chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) compound.

(1) Note. An organic halogen compound is one wherein halogen is attached directly or indirectly by nonionic bonding to carbon of an organic compound. Organic chalcogen compound is similarly defined.

(2) Note. See Notes to the Class Definition for the definition of organic compound.
