Dimorpholinomethane 3D Model — CAS 5625-90-1

Dimorpholinomethane (C9H18N2O2, CAS 5625-90-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. No legend required: the element symbol is engraved on each atom.

Start with the ring system: Dimorpholinomethane has two 6-membered rings; in total the model carries 32 bonds (all of them single). Students work from the model back to the formula C9H18N2O2: the symbol count is 9 C + 18 H + 2 N + 2 O, or 31 atoms all told. Spot-the-group challenge: can students find the two ether linkages (C-O-C) and the two tertiary amino groups (-NR2)? Lesson link: amines and basicity. Natural follow-up models: Dtdm (CAS 103-34-4) and 1,4-dioxane (CAS 123-91-1), close enough in structure for a spot-the-difference task.

MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: give each table a model and have students write the formula from the engraved atoms.

A ball-and-stick model of Dimorpholinomethane 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: 346,690 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: Bis(morpholino)methan (de).
