The molecule is built on a piperazine ring, a saturated six-membered heterocycle with two nitrogens positioned opposite each other (para relationship). Each nitrogen atom carries a distinct substituent:
1. On one nitrogen: a 2-hydroxyethyl chain (-CH2-CH2-OH).
2. On the other nitrogen: a tertiary carbon substituent, where the carbon is bonded to:
   - the piperazine nitrogen,
   - two methyl groups (-CH3), and
   - a thiol group (-SH).
