Class Information
Number: 558/271
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Carbonate esters (i.e, compounds having the -o-c(=o)o- group bonded directly to at least one carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon) > Benzene ring bonded directly to the -o-c(=o)o- group > Additional chalcogen bonded directly to the benzene ring
Description: Compounds wherein the benzene ring is bonded directly to an additional chalcogen (i.e., oxygen, sulfur, selenium, or tellurium).
