Class Information
Number: 534/643
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Azo > Fiber- or substrate-reactive azo compound > Alkylene, alkenyl, alkenylene, alkynyl or alkynylene attached directly or indirectlyto a ring by nonionic bonding > Alkylene, alkenyl or alkenylene bonded directly to carboxamido, urea or -c(=x)-, wherein x is chalcogen, which group is between a ring and the alkylene, alkenyl or alkenylene
Description: Compounds wherein an alkylene, alkenyl or alkenylene chain is bonded directly to a -- group, wherein X is chalcogen (i.e., oxygen, sulfur, selenium or tellurium), to a -C , group or to a N--N group, which group is between the chain and a ring.
