The molecule is based on a benzophenone core, where two benzene rings are connected through a central carbonyl group (phenyl-C(=O)-phenyl).

On one of the benzene rings of the benzophenone:
- At the para position relative to the carbonyl linkage, the ring carbon carries a primary amino group (-NH2).
- At the meta position to the carbonyl (and ortho to the amino substituent), the ring carbon is bonded to the nitrogen of an amide group (-C(=O)-NH-). The carbonyl carbon of this amide is directly attached to a pyridine ring (a six-membered aromatic ring containing one nitrogen).

On the pyridine ring:
- The ring nitrogen is meta to the amide attachment point.
- The carbon located between the amide linkage and the pyridine nitrogen bears a methyl-thio substituent (-S-CH3).
