DEFINITION

Classification: 508/495

With organic non-carboxylic acid ester chalcogen compound or nitrogen compound:

(under subclass 485) Compositions which contain, in addition to the specified carboxylic acid ester, an organic nitrogen compound or an organic chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) compound that is not a carboxylic acid ester.

(1) Note. An additional carboxylic acid ester may be present that is not the specified carboxylic acid ester of subclass 485, provided there is also present one of an organic nitrogen compound or an organic chalcogen compound that is not a carboxylic acid ester.

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

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