Class Information
Number: 534/750
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 > Having -c(=x)-, wherein x is chalcogen, attached indirectly by nonionic bonding to the acyclic carbon to which the other two acyclic carbons are bonded
Description: Compounds wherein a -C- group, in which X is chalcogen (i.e., oxygen, sulfur, selenium or tellurium), is attached indirectly by nonionic bonding to the acyclic carbon to which the other two acyclic carbons are bonded.
