1. The molecule's core is a five-membered 2-pyrazoline ring. Number the atoms clockwise as follows:
   - Atom 1: A nitrogen atom bearing an additional five-membered ring (described below).
   - Atom 2: A nitrogen atom.
   - Atom 3: A carbon atom substituted with a methyl group and double-bonded to Atom 2.
   - Atom 4: A carbon atom forming an E-configured azo linkage (-N=N-) to a phenol ring. In this linkage, the attached benzene ring has a hydroxyl group at the meta position relative to the azo bond.
   - Atom 5: A carbon atom featuring a double-bonded oxygen (a carbonyl group).

2. The secondary ring is a thiazole ring, an aromatic heterocycle composed of three carbon atoms, one nitrogen (located at position 3), and one sulfur (at position 1). Here, the carbon at position 2 is connected to the pyrazoline ring described above, while the carbon at position 4 is substituted with a para-methylphenyl group (i.e., a methyl group positioned at the para location relative to the thiazole connection).
