2-Ethoxythiazole (CAS: 15679-19-3) | Green, Nutty, Vegetal Aroma

2-Ethoxythiazole (CAS: 15679-19-3) is a high-purity heterocyclic aroma compound belonging to the thiazole family, widely recognized for its distinctive and complex olfactory profile. This compound exhibits a unique combination of green, nutty, vegetal, and earthy notes, with characteristic undertones reminiscent of fresh tomato leaf, roasted peanuts, green beans, and mushroom. These sensory properties make it a highly valuable ingredient in the development of authentic savory and vegetable-type flavor systems.

With a molecular formula of C₅H₇NOS, 2-Ethoxythiazole presents as a colorless to pale yellow liquid at room temperature, characterized by a powerful and diffusive odor. The compound demonstrates good solubility in ethanol, propylene glycol, and most organic solvents commonly employed in flavor and fragrance formulations. It is manufactured under controlled conditions to ensure consistent purity, typically exceeding 98%, with rigorous quality control applied to every production batch.

In flavor applications, 2-Ethoxythiazole is extensively utilized to create realistic vegetable profiles, particularly tomato, green bean, pea, and mushroom flavors. Its green, slightly earthy character enhances the freshness of vegetable formulations, while its nutty undertones contribute to roasted nut profiles such as peanut, hazelnut, and pistachio. The compound is also employed in savory snack seasonings, where it adds complexity to potato chip, cracker, and extruded snack applications. Additionally, it finds use in culinary-type flavors for soups, sauces, and ready meals, providing authentic cooked vegetable notes that enhance overall palatability.

Beyond the savory category, 2-Ethoxythiazole serves as a valuable component in certain fruit flavor systems, particularly those requiring green or unripe nuances, such as green apple, green melon, and tropical fruit profiles. In fragrance compositions, this versatile ingredient contributes fresh, green, and slightly earthy accords that complement gardenia, jasmine, and other white floral compositions, as well as adding naturalistic dimensions to herbal and fougère-type fragrances.

Each batch undergoes comprehensive quality control, including gas chromatography analysis to verify purity, organoleptic evaluation to confirm the characteristic aroma profile, and physical property testing to ensure compliance with established specifications. The product is manufactured in accordance with applicable regulatory standards for flavor and fragrance ingredients.
