2-Acetyl Pyrazine is a flavor and fragrance ingredient in the pyrazine family, with a characteristic odor reminiscent of toasted cereals, popcorn, toasted bread and dry nuts. Even at very low dosage, it already delivers a warm, slightly sweet impression, evoking buttery popcorn, golden baked crusts and breakfast cereals. Thanks to its lightly roasted and faintly smoky facets, 2-Acetyl Pyrazine is widely used to bring realistic gourmand, nutty and cereal effects into fragrance compositions.

In aroma and flavor applications, 2-Acetyl Pyrazine CAS# 22047-25-2 is commonly used in food-related profiles (vanilla, caramel, chocolate, coffee, nut), tobacco notes, snack flavors, as well as in some niche perfumes with culinary or warm smoky characters. Just a trace amount is enough to deepen the accord, increase realism and enhance tenacity in popcorn, chestnut, sunflower seed, almond and cereal notes. When combined with vanilla, lactonic, caramel and cocoa notes, 2-Acetyl Pyrazine helps the overall accord become rounder, richer and more mouthwatering.

With its strong odor profile, very low detection threshold and excellent base-note boosting effect, 2-Acetyl Pyrazine is an almost indispensable building block in the palette of perfumers and flavorists who want to create roasted, toasted, nutty and modern gourmand accords. It is suitable for use in fine fragrances, room sprays and bakery-inspired candles, as well as in snack, bakery and nutty beverage flavor constructions where an authentic roasted grain and nut character is desired.
