Class Information
Number: 546/37
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 > Heptacyclo ring system having the six-membered hetero ring as one of the cyclos > Plural ring hetero atoms in the heptacyclo ring system > Ring carbon is shared by three of the cyclos (e.g., perylene tetracarboxylic acid diimide, etc.)
Description: Compounds wherein one ring carbon is a member of three of the cyclos in the heptacyclo ring system (i.e., peri-fusion).
