Class Information
Number: 549/70
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) > Sulfur containing hetero ring (e.g., thiiranes, etc.) > The hetero ring is five-membered > Having -c(=x)-, wherein x is chalcogen, bonded directly to the hetero ring
Description: Compounds wherein --, in which X is chalcogen, (i.e., oxygen, sulfur, selenium, or tellurium), is bonded directly to the hetero ring.
