Acetylpyrazine

CAS: 22047-25-2

Overview

Acetylpyrazine (CAS 22047-25-2 ), also identified by FEMA 3126 , is a synthetic flavoring compound used in food and fragrance applications. It delivers a characteristic roasted, nutty, popcorn-like aroma that is difficult to replicate with natural alternatives.

Formulators rely on it to build or enhance cooked, toasted, and grain-like flavor profiles at low use levels. In food flavoring, it is used to create or reinforce roasted notes in snack seasonings, bakery products, and savory blends.

Popcorn and corn-based snack flavors depend heavily on this compound to achieve authentic character. In beverage applications, it contributes roasted depth to coffee, cocoa, and malt-flavored drink formulations for a more robust profile.

Fragrance and personal care formulators incorporate it into compositions targeting smoky, gourmand, or tobacco-adjacent scent profiles. It is highly effective at low concentrations, making it a cost-efficient choice for complex aromatic builds.

The compound is supplied as a liquid at room temperature and is available in commercial flavor-grade purity, typically 98–99%+. It is sold in small packaging for flavor house sampling through to drum quantities for industrial blending.

Buyers should confirm compliance with established industry regulations and review supplier documentation when sourcing for food-grade use. This ensures the material meets the necessary safety and quality benchmarks for global distribution.
