The molecule consists of two benzene rings, R1 and R2, connected by a long substituent chain.
- Ring R1 carries a methoxy group (-OCH3) at the position para to the connecting chain.
- Ring R2 has no additional substituents.

Connecting chain (from R1 to R2):
  1. The chain begins with an ether linkage and an ethylene fragment: R1-O-CH2-CH2-.
  2. This fragment is further attached to a sulfoxide sulfur: R1-O-CH2-CH2-S(=O)-.
  3. The sulfur continues to a methylene group: R1-O-CH2-CH2-S(=O)-CH2-.
  4. That methylene is bonded to a carbonyl carbon, forming an ester linkage: R1-O-CH2-CH2-S(=O)-CH2-C(=O)-O-.
  5. The ester oxygen extends into a straight three-carbon chain that terminates at ring R2: R1-O-CH2-CH2-S(=O)-CH2-C(=O)-O-CH2-CH2-CH2-R2.

No stereochemical features are defined.
