Class Information
Number: 534/745
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 > Two azo groups attached indirectly to each other by nonionic bonding > Each azo group is bonded directly to an acyclic carbon which is bonded directly to two acyclic carbons, each of which is double or triple bonded to an atom
Description: Compounds in which each of the two azo groups is bonded directly to an acyclic carbon, which carbon is additionally bonded directly to two acyclic carbons, each of which is double or triple bonded to an atom.
