4-(Piperidin-1-yl)benzaldehyde 3D Molecular Model — CAS 10338-57-5

4-(Piperidin-1-yl)benzaldehyde (C12H15NO, CAS 10338-57-5) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol.

Most printable molecule files rely on colour coding, yet the STL format carries no colour and a single-filament print loses it entirely. Each atom of a MolGod model is engraved with its element symbol, turning a plain print into a self-explaining teaching object. The project exists to put these files in teachers' hands, so that identifying atoms becomes quick and the lesson can move on to how atoms interact. No CAD skills are needed on the teacher's side; the structure, geometry and labels come ready in one file. Teachers and researchers can find the project rationale and validation plan at How the engraved atom letters are designed.

Look at the skeleton first: 4-(Piperidin-1-yl)benzaldehyde contains two 6-membered rings, one of them aromatic, and students can trace 30 bonds (23 single, 1 double and 6 aromatic, drawn in Kekulé form). Students work from the model back to the formula C12H15NO: the symbol count is 12 C + 15 H + 1 N + 1 O, or 29 atoms all told. Ask the class to locate the aldehyde group (-CHO) and the tertiary amino group (-NR2) and name each one. Use it when you teach aromaticity and delocalised electrons, the carbonyl group (C=O), as well as amines and basicity. Place it beside 4-Hydroxybenzaldehyde (CAS 123-08-0) and Benzaldehyde (CAS 100-52-7) and ask students which features are shared and which are not.

Free for education: MolGod.org publishes engraved molecular models for teachers, students and schools. 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. When you publish a photo, a worksheet or a remix, CC BY-SA 4.0 requires you to credit "MolGod.org" as the author of the model, link to the original and to the licence, indicate any changes and share remixes under the same licence (the ready attribution line is below). No sign-up, no fees and no review required. 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. The comment section is open for discussion: how did you introduce this molecule, and what did your students notice first? Your curriculum needs a specific compound? Share the CAS number and we will create the engraved model.

A ball-and-stick model of 4-(Piperidin-1-yl)benzaldehyde 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: 351,252 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
