Class Information
Number: 546/155
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 > Polycyclo ring system having the six-membered hetero ring as one of the cyclos > Bicyclo ring system having the six-membered hetero ring as one of the cyclos > Quinolines (including hydrogenated) > Chalcogen attached directly to the six-membered hetero ring by nonionic bonding > Plural chalcogens attached directly to the six-membered hetero ring by nonionic bonding
Description: Compounds in which at least two chalcogens (i.e., oxygen, sulfur, selenium, or tellurium) are attached directly to the six-membered hetero ring by nonionic bonding.
