  • Applications

    Hydroxy-Gamma-Sanshool (CAS 78886-66-5) is a sensory-active compound with real-world applications across several industries: it may be used in food processing and flavor formulations to impart peppery taste and a tingling sensation; it is evaluated for fragrance and perfumery applications to emulate Sichuan pepper notes; it is studied as a sensory additive in cosmetics and personal care to enhance tactile experience on skin or lips; and it serves as an intermediate in organic synthesis for specialty flavor- or fragrance-related chemicals.
