KJPRLNWUNMBNBZ-QPJJXVBHSA-NChecked against PubChem and Wikidata on 2026-10-02 (identifier check run 37063263965). Every name SmellBook uses must resolve to the same single PubChem compound.
SmellBook lists a molecule only where a VERIFIED claim names it, in the role and scope that claim states. A molecule reported in a smell's evidence is not the whole smell: most smells come from many compounds together, and the studies measured particular samples, such as one cultivar, an essential oil or a cooked product.
