Class Information
Number: 552/108
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 is part of a polycyclo ring system (e.g., naphthyldiphenylcarbinol, etc.)
Description: Compounds wherein a polycyclo ring system is bonded directly to the acyclic carbon.
