A roasted/nutty fragrance pyrazine — GRAS as a food flavor, used at trace levels in cosmetics.
2,3-Diethylpyrazine (CAS 15707-24-1) is a diazine heterocycle with a distinctive roasted, nutty, coffee-like aroma. It is primarily known as a GRAS food flavor (FEMA 3136) and is authorized as a flavor in many jurisdictions. In cosmetics it appears as a minor fragrance ingredient used at ppm levels. Its toxicological profile has been characterized via flavor-use assessments and is considered acceptable at such low exposures. In finished products the compound is used far below any reasonable irritation or sensitization threshold.
