Pentamidine 3D Molecular Model — CAS 100-33-4

Pentamidine (C19H24N4O2, CAS 100-33-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid. Turn the model in your hand to see the shape of Pentamidine: two 6-membered rings, both aromatic, and 50 bonds in total (36 single, 2 double and 12 aromatic, drawn in Kekulé form). How many atoms can the class find? The engraved spheres give 19 C + 24 H + 4 N + 2 O, so the answer should be 49. Teache…
