8-Hydroxyquinoline 3D Model — CAS 148-24-3

8-Hydroxyquinoline (C9H7NO, CAS 148-24-3) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.

At its heart, 8-Hydroxyquinoline is built around two 6-membered rings, fused along a shared edge, both aromatic. The model shows 19 bonds: 8 single and 11 aromatic. Quick starter: ask students to count the engraved symbols (9 C + 7 H + 1 N + 1 O) and check that they add up to 18 atoms and the formula C9H7NO. Spot-the-group challenge: can students find the phenolic hydroxyl group (Ar-OH) and the pyridine-type ring nitrogen? Use it when you teach aromaticity and delocalised electrons, fused ring systems, heteroaromatic rings (nitrogen inside an aromatic ring), as well as phenols and hydrogen bonding. Its closest structural relatives in the MolGod.org collection are 2,2':6',2''-Terpyridine (CAS 1148-79-4) and 6-Aminoquinoline (CAS 580-15-4); printing them side by side makes a quick compare-and-contrast exercise.

MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: print one per group and let students check the structure against the formula.

A ball-and-stick model of 8-Hydroxyquinoline with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 251,112 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
