  • Applications

    The compound (2R)-(+)-furaneol (CAS 131222-82-7) is a fragrance-active compound widely used as a flavoring agent in foods and beverages to impart strawberry and caramel notes. In perfumery and cosmetics, it serves as a fragrance ingredient; in household products such as cleaners and air fresheners, it contributes a fruity odor. It is also used as an intermediate or building block in aroma-chemical syntheses for industrial manufacturing. In certain polymer, coating, or packaging formulations, it may be added as an aroma additive to impart fruity notes, subject to local regulations and formulation limits.
