Distinctive Sweet Odor: It has a very sweet, caramel-like odor that is highly persistent, offering a unique and appealing aroma in various applications.
Versatile Flavor Profile: Ethyl Maltol delivers a sweet, fruity taste with an initial bitter-tart flavor, providing a complex and dynamic flavor experience in food and beverages.
Efficient Synthesis: Ethyl Maltol can be synthesized through a one-pot process, offering a streamlined method of production that enhances its availability for commercial use.
Ethyl Maltol CAS# 4940-11-8
Ethyl maltol forms white crystals with a melting point of 90–91°C and has a strong, sweet, caramel-like odor. It is 4 to 6 times more potent than maltol. Several synthetic methods have been developed for its production. In one such method, ethylfurfuryl alcohol is reacted with halogens to form 4-halo-6-hydroxy-2-ethyl-2H-pyran-3(6H)-one, which can directly undergo aqueous hydrolysis to yield ethyl maltol without the need for isolation. Ethyl maltol has a distinct, sweet, fruit-like odor with remarkable persistence and a sweet, fruity taste that initially carries a bitter-tart flavor, which fades quickly. It is significantly stronger than maltol, making it an effective flavoring agent.

Product Application of Ethyl Maltol CAS# 4940-11-8
Ethyl Maltol serves as a flavor and fragrance enhancer in a variety of foods, particularly in baked goods, beverages, and synthetic berry and citrus flavorings. It is also used to mask undesirable flavors in products such as tobacco, cough syrup, vitamins, cosmetics, and saccharin-containing items. Ethyl Maltol is a white crystalline powder with a distinct, fruity odor and a sweet taste. It has a melting point of 90°C and is sparingly soluble in water and propylene glycol, but readily dissolves in alcohol and chloroform. It is produced through chemical synthesis.
