Named in 1 VERIFIED claim about 1 Atlas entry: Rubber.
Reported volatile · the claim says “along with odorous”
Headspace analysis of 14 rubber types at the drying temperature used in rubber processing found volatile fatty acids such as acetic, propanoic, butanoic, pentanoic and hexanoic acids often above their odour detection thresholds, along with odorous trimethylamine, p-cresol, indole and phenol.
Scope: Natural rubber during processing and storage, not finished rubber products. CLM-RUBBER-001 ↗
SIKJAQJRHWYJAI-UHFFFAOYSA-NChecked against PubChem and Wikidata on 2026-10-03 (identifier check run 37117518739). 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.
