Class Information
Number: 552/109
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.) > An acyclic alkylene group is bonded directly to nitrogen and to chalcogen, cyano, carbonyl or additional nitrogen (e.g., n-hydroxyalkyl, n cyanoalkyl, n-sulfatoalkyl, aminoalkylamino groups, etc.)
Description: Compounds wherein (a) nitrogen and (b) cyano, carbonyl, additional nitrogen, or chalcogen (i.e., oxygen, sulfur, selenium or tellurium) are bonded to the same acyclic alkylene group.
