2-Acetylpyrazine

2-Acetylpyrazine is a heterocyclic aromatic compound characterized by its distinctive nutty, popcorn-like, and roasted grain scent profile, which is also found naturally in cooked foods such as bread and coffee. In cosmetic formulations, it is used as a fragrance ingredient to impart warm, gourmand, or toasted nuances to perfumes, body care products, and hair care formulations. Formulators select it for its ability to contribute complex, food-inspired olfactory depth at low usage concentrations, typically well below 1%.
