Class Information
Number: 548/136
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.) > The five-membered hetero ring consists of chalcogen, plural nitrogens, and carbon > 1,3,4-thiadiazoles (including hydrogenated)
Description: Compounds in which the five-membered hetero ring has sulfur in the 1-position, nitrogens in the 3- and 4-positions, and carbons in the remaining two positions.
