The molecule has a benzothiazole core, consisting of a benzene ring fused into the two adjacent carbons of a 1,3-thiazole ring (a five-membered aromatic ring containing sulfur and nitrogen in a meta relationship).

For clarity, number the ring system anticlockwise starting from the sulfur atom: S1-C2-N3-C4 (junction 1)-C5-C6-C7-C8-C9 (junction 2), and back to S1.   

Substitution pattern on this ring system:

- C2 bears a methyl group (-CH3).
- C7 bears a primary amino group.
- C6 is linked to a pyrazole ring via a short linker consisting of a secondary amine (-NH-) bonded to C6, and a methylene group (-CH2-) attached to the pyrazole.
    - The pyrazole is a five-membered aromatic ring with two adjacent nitrogens: one nitrogen carrying hydrogen denoted as N-alpha, the adjacent nitrogen as N-beta.
    - The methylene linker attaches to the carbon meta to both nitrogens.
    - At the carbon adjacent to the N-beta, there is an additional methyl substituent.
