- The molecule contains a five-membered ring with two adjacent nitrogens at positions 2 and 3 and a sulfur at position 5, leaving positions 1 and 4 as carbons. The carbon-nitrogen pairs at positions 1-2 and 3-4 form double bonds.
- At ring carbon 1, there is a three-carbon straight chain. The third carbon in this chain is substituted with an amino group (-NH-) that carries a two-carbon extension ending in a methoxy (-OCH3) group, forming -NH-CH2-CH2-OCH3.
- At ring carbon 4, there is a phenyl ring substituted with two adjacent hydroxyl groups (a catechol moiety). The carbon directly attached to ring carbon 4 is designated as position 1 of the phenyl ring, while the hydroxyl groups are positioned at carbons 3 and 4 of the phenyl ring.
- No other substituents or stereochemical features are present.
