pentamethylenetetrazol = tetrazole (opaque) = penta + methylene + tetrazol

The term is a specialized chemical name built from technical combining forms; its meaning is not inferable by average learners from the component parts.

Etymology

Pentamethylenetetrazol is a long chemical name that describes the parts inside the molecule: penta- means 'five', methylene is a 'small chemical link', and tetra- in tetrazol means 'four' and points to a four-part ring. So the name is long because it simply tells chemists which 'five' and 'four' parts make up the drug.
