2-(Methylthio)pyrazine is a potent sulfur-containing flavor compound (FEMA 3209) that delivers intense roasted, nutty, and meaty aromas with a characteristic sulfury nuance. Widely used in savory applications, it enhances meaty profiles in processed snacks, sauces, and ready-to-eat meals. The compound is particularly valued for replicating roasted coffee and peanut flavors at low concentrations (0.1-5 ppm). In fragrance formulations, it adds depth to savory and roasted accords. With excellent thermal stability, it performs well in both high-temperature food processing and functional fragrance systems. The methylthio group contributes to its distinctive aroma profile, making it essential for authentic savory flavor creation.
