Starts from a piperazine ring (a fully saturated six-member ring with two nitrogen in opposite position). 
The core of the molecule is a piperazine ring, which is a six-membered saturated heterocycle containing two nitrogen atoms in para positions.

- One of the ring nitrogens is methylated, carrying a methyl substituent (-CH3).
- Meta to this methylated nitrogen (i.e., on the carbon two atoms away along the ring), a side chain extends outward.

Side chain description:
- The side chain is a two-carbon saturated linker.
- At the end of this linker, the chain is attached to a thiophene ring, a five-membered aromatic heterocycle with one sulfur atom. The point of attachment is at a carbon ortho to the sulfur atom in thiophene. At the position meta to the ring sulfur (and also meta to the attachment point), the ring carbon bears a bromine substituent.

Branch on the linker:
- On the second carbon of the linker (the one closer to the thiophene ring), there is an additional branch.
- This branch is a methylamino unit: the linker carbon bonds to a nitrogen atom, and that nitrogen in turn is bonded to a methyl group.
