This molecule's main framework is a five-membered thiophene ring bearing two substituents. Numbering the ring so that sulfur is at position 1:
- At C2 of the thiophene, there is a -CH2- linkage to one of the nitrogens in a six-membered piperazine ring (which contains two nitrogens at opposite positions, with one nitrogen bonded to this -CH2-). The other nitrogen in the piperazine carries a carbonyl group. The carbonyl carbon is directly attached to a pyridine ring (a six-membered aromatic ring with one nitrogen); within the pyridine, the nitrogen is at the meta position relative to the carbonyl attachment, and a methyl substituent is present at the para position relative to that attachment.
- At C5 of the thiophene, a phenyl ring (monofluorobenzene) is attached, bearing a single fluorine substituent at the meta position relative to the point of attachment.
