The molecule is built around a tertiary nitrogen, which is bonded to three substituents:
1. A phenyl ring, attached directly to the nitrogen. On this ring, the para carbon relative to the attachment point carries an ethoxy group (-O-CH2-CH3).
2. A two-carbon chain (-CH2-CH2-), where the terminal carbon (second in the chain) is substituted with two ethoxy groups.
3. A quaternary carbon center, which itself is bonded to:
   - the same tertiary nitrogen described above,
   - two methyl groups, and
   - a carboxylic acid group (-COOH).
