The molecule is built on a pyrazole ring (five-membered aromatic ring with adjacent nitrogens at positions 1 and 2).

Substitution pattern (clockwise from N1):
1. N1 is methylated, giving an N-CH3 group.
2. C3 carries a straight n-propyl group -CH2-CH2-CH3.
3. C5 carries an anilide-type substituent, consisting of an exocyclic -NH- group attached directly to the ring carbon. The nitrogen is bonded to a carbonyl group (-C(=O)-), which is then extended into a three-carbon chain (-CH2-CH2-CH2-) terminating in a thioether (-S-CH3).

No other heteroatoms, stereocenters, or double-bond geometries are present.
