Number: 548/304.7
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 five-membered having two or more ring hetero atoms of which at least one is nitrogen (e.g., selenazoles, etc.) > 1,3-diazoles (including hydrogenated) > Polycyclo ring system having the diazole ring as one the cyclos > Bicyclo ring system having the diazole ring as one of the cyclos > The other ring is a benzene ring > Additional hetero ring attached directly or indirectly to the diazole ring by nonionic bonding (e.g., methyl( 5-[2-(2-thienyl)-1,3-dioxolan -2-yl]-1h-benzimidazol-2-yl) carbamate, etc.)
Description: Compounds wherein an additional hetero ring is attached directly or indirectly to the 1,3-diazole ring by nonionic bonding.

Class Number Class Name Patents
548/306.1 The additional hetero ring contains nitrogen as the only ring hetero atom [e.g., 2-(2`-imidazolin-2`-yl)-benzimidazole; 1-p-chlorophenyl-3- pyrrolidin-1`- yl-propyl benzimidazolone, etc.] 401
548/305.1 The additional hetero ring is a cyclo in a polycyclo ring system (e.g., benzofuranyl-benzimidazole, etc.) 343
