  • Applications

    Pyrazine, 2-((2-furanylmethyl)thio)-5-methyl-, CAS 59303-08-1 may be used as an odorant and aroma component in perfumery and flavor applications, contributing roasted, nutty notes associated with pyrazine derivatives. It is often evaluated for use as a fragrance ingredient in cosmetics and personal care products, and can serve as a building block or intermediate in the industrial synthesis of more complex pyrazine-based aroma compounds. In addition, it may be employed in household cleaning products to impart specific odor profiles, and as a synthetic intermediate in related flavor/fragrance chemistry.
