DEFINITION

Classification: 564/1.5

(under subclass 1) Compounds wherein urea, per se, of thiourea, per se, forms an adduct or inclusion compound with an organic compound.

(1) Note. by adduct or inclusion compound is meant a type of complex in which the urea or thiourea is bound with another suitable chemical without changing the chemical character of either the urea-thiourea or of the other chemical; the respective molecules will be unaltered in their chemical nature and the individual compounds may readily be constituted and isolated.

(2) Note. An example of a compound provided for herein is the adduct of urea and an alkane.
