The molecule is a six-membered aromatic ring numbered from carbon-1 to carbon-6. A methyl group is attached at carbon-1, and a carboxylic acid group is located at carbon-4 in the para position. At carbon-2, the ring carries a more extended side chain. This side chain begins with an ether oxygen bonded directly to the ring, which leads into a short two-carbon saturated spacer. The chain then connects to a sulfonyl group, where the sulfur atom is doubly bonded to two oxygens. Finally, the sulfur is bonded to an isopropyl group, a carbon bearing two methyl substituents.
