Methyl 2-Bromo-4-nitrobenzoate 3D Molecular Model — CAS 100959-22-6

Methyl 2-Bromo-4-nitrobenzoate (C8H6BrNO4, CAS 100959-22-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour.

At its heart, Methyl 2-Bromo-4-nitrobenzoate is built around one aromatic 6-membered ring. The model shows 20 bonds: 12 single, 2 double and 6 aromatic, drawn in Kekulé form. A five-minute warm-up: read the symbol on every sphere and write down the totals (8 C + 6 H + 1 Br + 1 N + 4 O = 20 atoms). Functional groups to find on the model: ester group (-COO-), nitro group (-NO2) and C-Br bond. Topics it supports in class: aromaticity and delocalised electrons, the carbonyl group (C=O), as well as organohalogen compounds and carbon-halogen bonds. Ask students what this molecule has in common with 4-Bromomethyl-3-nitrobenzoic acid (CAS 55715-03-2), then what sets them apart; the molecular formula is shared.

MolGod.org offers this engraved model free to anyone teaching or learning chemistry. Teachers: give each table a model and have students write the formula from the engraved atoms.

A ball-and-stick model of Methyl 2-Bromo-4-nitrobenzoate 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: 293,682 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
