MOLECULE
Named in 1 VERIFIED claim about 1 Atlas entry: Wood Smoke.
Key odorant · the claim says “among its most potent odorants”
A gas chromatography–olfactometry study of condensed mixed-hardwood smoke found phenolic compounds such as guaiacol, 4-methylguaiacol and 4-methylsyringol among its most potent odorants, alongside compounds such as 2,3-butanedione.
Scope: Supports the odorants of one condensed hardwood smoke studied for food smoking; open fires, other woods and burning conditions can differ. CLM-WOODSMOKE-001 ↗
PETRWTHZSKVLRE-UHFFFAOYSA-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.
