A benzene ring with three substituents in a 1,3,5 (meta) pattern: two are methyl groups (-CH3), and the third is the long side chain described below.

Side chain consists of 11 atoms in total:
  - Number the side chain atoms from the ring outward as 1 to 11.
  - Atoms 4 and 8 are nitrogens; all others are carbons.
  - Double bonds: 3=4 and 8=9 (both are C=N; no E/Z specified).
  - All other bonds in the chain are single.

Substituents on the side chain:
  - C3 bears a hydroxyl group.
  - C9 bears a hydroxyl group.
  - C10 bears an additional methyl.
