2-Methoxypyrazine is a specialty chemical used in flavor and fragrance formulations for its potent green, earthy, and vegetable-like aroma, often described as reminiscent of raw potatoes, green peas, or bell peppers. It is commonly incorporated into artificial flavorings for savory foods such as potato chips, vegetable-based snacks, and soups to impart authentic green notes. In perfumery, it enhances natural and chypre compositions by adding depth with realistic earthy and vegetal facets, particularly in niche scents. Its high potency allows effective use at very low concentrations, typically in parts per billion.
