Morphology

purine = pur + ine

A technical chemical name formed from a non-productive combining form plus the chemical suffix '-ine', so learners cannot derive the biological meaning from common English components.

Etymology

Purine was named in the 19th century from chemicals found in urine, so a helpful way to remember it is to connect purine with 'uric acid'. Purine makes the building parts of DNA and RNA (like adenine and guanine), and when purines break down they form 'uric acid', which explains why too much can cause gout.
