Class Information
Number: 546/344
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) > Hetero ring is six-membered consisting of one nitrogen and five carbons > Chalcogen attached indirectly to the six-membered hetero ring by nonionic bonding (e.g., sulfato betaines, etc.) > The chalcogen is in an -oh or -om group (m is group ia or group iia light metal)
Description: Compounds in which the chalcogen is part of an -OH or -OM group; wherein M is a Group IA or Group IIA metal having a specific gravity less than four.
