2,4,6-Tris((dimethylamino)methyl)phenol 3D Molecular Model — CAS 90-72-2

2,4,6-Tris((dimethylamino)methyl)phenol (C15H27N3O, CAS 90-72-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every sphere shows which element it is through an engraved symbol, not a colour code.

Ordinary molecular STL files leave students guessing, because the colour scheme that identifies atoms on screen does not survive printing. We build the label into the model: each sphere bears its recessed element symbol, readable by eye and by fingertip. Our goal is to let students understand on their own how the atoms are arranged, how they are bonded and what the 3D geometry looks like, straight from the model in their hands. Teachers get the structure and its atom labels in a single download, which removes the slowest steps before a classroom print. Background, references and the planned classroom study: How the engraved atom letters are designed.

Let the group sketch what they see in 2,4,6-Tris((dimethylamino)methyl)phenol, namely one aromatic 6-membered ring; afterwards they compare the sketch with the 46 bonds on the model (40 single and 6 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 15 C + 27 H + 3 N + 1 O, 46 in total. Link the model to intermolecular forces through its hydrogen-bond capacity: 4 acceptors, 1 donor (computed). Functional groups to find on the model: phenolic hydroxyl group (Ar-OH) and three tertiary amino groups (-NR2). Worth bringing out when the syllabus reaches aromaticity and delocalised electrons, phenols and hydrogen bonding, as well as amines and basicity.

Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: pass the model round at the start of the lesson, before showing any diagram.

This printable molecule is free to use in lessons, clubs and workshops. If you share a photo, a lesson or an adapted version, the licence (CC BY-SA 4.0) asks for credit to "MolGod.org" as the model's author, a link to the original and to the licence text, a note of what you changed, and the same licence for adaptations; the attribution line below is ready to copy. You don't need an account, you don't pay anything, and a review is entirely up to you. Your comments decide what we improve next, from engraving depth to which molecules we add. Leave a review below or contact us at Write to the MolGod team. Curious about bond angles, isomers or where this compound appears in everyday life? Ask below and let's discuss it together. Just send us a CAS number: we will build a custom engraved 3D model of that molecule for you.

A ball-and-stick model of 2,4,6-Tris((dimethylamino)methyl)phenol 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: 518,628 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
