DEFINITION

Classification: 560/19

Nitrogen in acid moiety other than as nitroso or isocyanate (e.g., amino acid esters, etc.):

(under subclass 8) Compounds wherein the acid radical contains covalently bonded nitrogen other than in the form of an isocyanate or nitroso group.

(1) Note. Compounds containing an isocyanate or a nitroso group are not per se excluded from this subclass, provided that the compounds also contain nitrogen in another form.

(2) Note. This subclass contains, for example: [figure] [figure]
