Class Information
Number: 552/111
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.) > Nitrogen, except as cyano, attached indirectly to a ring by acyclic nonionic bonding (e.g., benzyl rosanilines, etc.)
Description: Compounds wherein a ring is attached to nitrogen, except as cyano, by acyclic nonionic bonding.
