Class Information
Number: 552/110
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 and a benzene ring are bonded directly to the same nitrogen (e.g., triphenylrosaniline, etc.)
Description: Compounds , wherein the same nitrogen is bonded to one of the rings and to a benzene ring.
