This molecule has a central sulfonyl sulfur atom (bearing two double-bonded oxygens) that carries two substituents: an ethyl group and a nitrogen atom. The nitrogen is connected via a single methylene group to a five-membered ring containing one sulfur and one nitrogen, arranged as S1-C2-N3-C4-C5. In this ring, the bonds between C2 and N3 and between C4 and C5 are double bonds. C5 is linked to the methylene bridge from the sulfonamide nitrogen, while C4 bears a methyl substituent. Additionally, C2 carries a pyridine ring (a six-membered aromatic ring in which a nitrogen is located at the meta position relative to the point of attachment).
