5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone
5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone, identified by CAS 27538-09-6, is a cyclic keto-enol compound belonging to the furanone family. Often referred to as homofuraneol, this chemical is recognized for its potent organoleptic properties, characterized by a distinctively sweet, caramel-like aroma with nuances of cooked fruit. It typically appears as a colorless to pale yellow liquid or solid, depending on its purity and temperature, and is valued for its high flavor impact even at low concentrations.
In industrial and research settings, this compound is handled as a specialized aroma chemical. It exhibits good stability in various medium-polarity solvents but requires careful storage away from light and heat to maintain its chemical integrity. Its unique molecular structure allows it to act as a critical building block in the synthesis of complex fragrance and flavor profiles, bridging the gap between sugary sweetness and savory depth in diverse chemical formulations.
• As a primary flavoring agent, this compound is extensively utilized to impart sweet, jammy, and caramelized notes to a wide range of food and beverage formulations. It is particularly effective in replicating the complex profiles of cooked strawberries, pineapples, and other red fruits, providing a “browned” or roasted sugar quality that enhances the overall sensory experience of confectionery and bakery products.
• In the fragrance industry, it serves as a versatile component in perfumery, where it contributes to gourmand and oriental scent profiles. Its ability to provide a warm, balsamic, and slightly malty undertone makes it a preferred choice for creating comforting and sophisticated aromas in personal care products, candles, and fine fragrances, often acting as a bridge between fruity top notes and heavier base notes.
• The chemical acts as a vital intermediate in synthetic organic chemistry, particularly in the development of novel aroma chemicals and bioactive molecules. Researchers utilize its reactive furanone ring to explore new derivatives, taking advantage of its specific substitution pattern to study structure-activity relationships in the context of olfaction and chemical signaling.
• It is frequently employed in the tobacco and vaping industries to modify flavor profiles, where it helps to soften harsh notes and introduce a smooth, sweet finish. By mimicking the natural chemistry of heat-treated sugars, it provides a realistic toasted character that is highly sought after in the formulation of specialty tobacco alternatives and aromatic blends.
