Class Information
Number: 552/106
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Acyclic carbon bonded directly to three benzene rings or to two benzene rings and a cyclohexadienyl ring, which acyclic carbon may not be bonded to a fourth carbon (e.g., triphenylmethane dyestuffs, etc.) > One of the rings, or a polycyclo ring system containing one of the rings, is bonded directly to -n=c=o or to -c(=o)oh (wherein h may be replaced by a group ia or iia light metal, or by substituted or unsubstituted ammonium)
Description: Compounds wherein-N=C=O or -C(=O)OH, in which H may be replaced by Group IA or IIA light metal or by substituted or unsubstituted ammonium, is bonded directly to one of the rings or to a polycyclo ring system containing one of the rings.
