Class Information
Number: 549/554
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.) > The hetero ring is three-membered consisting of one oxygen and two carbons > Chalcogen attached indirectly to the hetero ring by nonionic bonding
Description: Compounds in which chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is attached indirectly to the oxirane ring by nonionic bonding.
