Peach furanone
CAS 3658-77-3
What Is Peach furanone?
Peach furanone is a synthetic aroma chemical that delivers an intensely sweet, juicy peach character. You’ll find it in fruity body care products, candies, and gourmand fragrances. This molecule matters because it captures the essence of ripe peaches with remarkable precision, allowing perfumers to create hyper-realistic fruit accords without relying on natural extracts.
Safety Profile
GENERALLY SAFEWhat Does Peach furanone Smell Like?
Peach furanone bursts with the syrupy sweetness of sun-warmed peaches still clinging to the pit, that perfect moment when juice drips down your chin. The top note has a slightly candied quality like peach gummies, quickly settling into the dense fleshiness of a yellow clingstone peach at peak ripeness. As it dries, it develops a subtle lactonic undertone reminiscent of peach skin’s velvety texture, with just a whisper of woody pit character that prevents it from being cloying.

Chemistry, Properties & Perfumer Guide
The Chemistry
Peach furanone belongs to the furanone class of heterocyclic compounds, specifically a γ-lactone with a furan ring. While furanones occur naturally in peaches and other stone fruits, commercial production typically involves synthesis from furfural derivatives. The molecule’s potency stems from its ability to activate multiple olfactory receptors simultaneously, creating a complex fruity perception despite its simple structure.
