DEFINITION

Classification: 560/25

Polycarbamic:

(under subclass 24) Compounds wherein the acid radical contains more than one carbamic acid group, at least one of which is esterfied.

(1) Note. This subclass also contains compounds where an unesterified carbamic acid has been converted into a salt or an acid halide. Where an unesterified carbamic acid group has been converted into an amide and only one esterified carbamic acid group is present, the compound is classified in the appropriate subclass dealing with monocarbamic acid esters.

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