Class Information
Number: 552/101
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.)
Description: Compounds under Class 532, ... , wherein either (a) three benzene rings or (b) two benzene rings and a cyclohexadienyl ring are bonded directly to the same acyclic carbon, which acyclic carbon may not be bonded to a fourth carbon.
