Class Information
Number: 558/274
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 > Two benzene rings bonded directly to the -o-c(=o)o- group (i.e., diaryl carbonates)
Description: Compounds wherein the -O-C(=O)O- group is bonded directly to two benzene rings.
