Class Information
Number: 534/742
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Azo > Azo bonded directly to an acylic carbon which is bonded directly to two acyclic carbons, each of which is double or triple bonded to an atom > Hetero ring attached indirectly to an azo group by nonionic bonding > The acyclic carbon, to which the other two acyclic carbons are bonded, is between the hetero ring and the azo group
Description: Compounds wherein the acyclic carbon, to which the other two cyclic carbons are bonded, is between the hetero ring and the azo group.
