DEFINITION

Classification: 560/37

The nitrogen is not bonded directly to a ring:

(under subclass 19) Compounds wherein the acid radical contains nitrogen which is not directly attached to a carbocyclic nucleus.

(1) Note. When the same N atom is directly attached to one carbocylic nucleus and indirectly attached to a second carbocyclic nucleus, it will always be considered as directly attached for classification, e.g., [figure]
