3-Mercaptopropionic Acid 3D Model — CAS 107-96-0

3-Mercaptopropionic Acid (C3H6O2S, CAS 107-96-0) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol. 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. The project aims to let a student work out the arrangement of atoms, the bonds and the geometry of the molecule independently, without a colour key and without waiting for the teacher. Preparation time drops for the teacher too: there is nothing to model, colour or annotate before sending the file to the printer. Curious about the science behind the engraving? The project page is at The story behind these engraved molecule models. There is not a single ring in 3-Mercaptopropionic Acid; 12 atoms are linked by 11 bonds in an open chain (10 single and 1 double). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 3 C + 6 H + 2 O + 1 S, which is 12 atoms. Ask the class to locate the carboxylic acid group (-COOH) and name each one. Students meeting the carbonyl group (C=O) for the first time can hold an example in their hands. Pair it with succinic acid (CAS 110-15-6) and adipic acid (CAS 124-04-9) from the same collection to compare closely related structures. Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: use it as a hands-on starter before drawing the structural formula on the board. Free to print and free to bring into any classroom. 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. There is no registration, no payment and no obligation to rate it. We build these models for learners, so your feedback guides us: leave a review below and tell us which detail would make the next molecule clearer. Or say hello at Ask us for another molecule. Curious about bond angles, isomers or where this compound appears in everyday life? Ask below and let's discuss it together. Every request counts: tell us which molecule you need and we will make its 3D model specially for your students.
