Chlorobutanol 3D Molecular Model — CAS 57-15-8

Chlorobutanol (C4H7Cl3O, CAS 57-15-8) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed.

Most printable molecule files rely on colour coding, yet the STL format carries no colour and a single-filament print loses it entirely. MolGod adds what the STL format leaves out by engraving the element symbol into each atom of the printed structure. Our intended outcome is simple: students who hold the model should know each atom immediately and use the lesson to understand the molecule's structure. For teachers it also saves preparation: the file is already modelled and labelled, so the only steps left are scaling and slicing. Read why we engrave the atoms, and which studies inspired the project: How the engraved atom letters are designed.

Follow the chain of Chlorobutanol from end to end: 15 atoms, 14 bonds (all of them single) and no ring anywhere. Use the engraved letters like a register: call out each element and tick it off until the class reaches 4 C + 7 H + 3 Cl + 1 O (15 atoms altogether). This molecule gives students these functional groups to identify: hydroxyl group (-OH) and three C-Cl bonds. A good fit for lessons on alcohols and hydrogen bonding, as well as on organohalogen compounds and carbon-halogen bonds. Want a comparison? The most similar structures in the MolGod.org collection are tert-Butanol (CAS 75-65-0) and 1-Chloro-2-methylpropan-2-ol (CAS 558-42-9).

MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: hand out printed copies and ask students to rebuild the structural formula from the model.

Download it, print it and use it in your teaching. Sharing it somewhere? The licence (CC BY-SA 4.0) needs four things: "MolGod.org" credited as the creator, links to the original and to the licence, a mention of any changes, and adaptations released under the same licence. The attribution text below covers the first two. You don't need an account, you don't pay anything, and a review is entirely up to you. Feedback is the most important part of this project: your review in the comments shows us how to improve the whole collection and build better models. Contact: Write to the MolGod team. Join the conversation: comments, questions and classroom stories are all welcome, and you can always contact us for anything more. Need another molecule? Contact us and we will prepare a 3D model specially for you, starting from its CAS number.

A ball-and-stick model of Chlorobutanol 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: 187,578 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: 1,1,1-Trichlor-2-methyl-2-propanol (de); cloretone (it); 1,1,1-trichloro-2-metylo-2-propanol (pl); 三氯叔丁醇 (zh).
