Class Information
Number: 549/292
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Oxygen containing hetero ring (e.g., dioxirane, etc.) > Lactones (i.e., -c(=x)o-, wherein x is chalcogen, is part of the hetero ring) > The lactone ring is six-membered > Additional chalcogen bonded directly to the lactone ring
Description: Compounds wherein an additional chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is bonded directly to the lactone ring.
