Safety Profile
USE WITH AWARENESSWhat Does 2-Furyl methyl ketone Smell Like?
2-Furyl methyl ketone delivers an intense caramelized sugar character with roasted nut undertones. The initial burst resembles burnt sugar dissolving in coffee, evolving into a persistent maple-like sweetness. In drydown, it reveals a subtle woody-balsamic facet that anchors gourmand compositions. The molecule behaves like liquid praline – rich, slightly smoky, and persistently sweet without becoming cloying.

Chemistry, Properties & Perfumer Guide
The Chemistry
2-Furyl methyl ketone belongs to the furanone class of heterocyclic compounds. While furanones occur naturally in roasted foods, this specific ketone is typically synthesized for fragrance use. The molecule features a furan ring substituted with an acetyl group at the 2-position, creating its characteristic caramel-like odor. Industrial production typically involves furfural derivatives through oxidation or condensation reactions.
