DEFINITION

Classification: 508/493

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

(under subclass 492) Compositions which contain, in addition to the specified carboxylic acid ester, an organic nitrogen compound, an organic halogen 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 492, provided there is also present one of an organic nitrogen compound, an organic halogen 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. Organic halogen compounds and organic chalcogen compounds are similarly defined.

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