  • Applications

    Guaiene (CAS 88-84-6) is a woody, smoky–spicy sesquiterpene hydrocarbon widely used in perfumery to build woody–amber accords, add depth and diffusion, and enhance longevity in fine fragrances, candles, personal care, and home care; in flavor applications, at trace levels it imparts subtle wood/smoke/tea nuances to fermented beverages, cocoa, savory spice profiles, and baked goods; in analytics and QC it serves as a natural marker and GC–MS reference standard for guaiac wood, patchouli, and agarwood/oud essential oils, supporting authenticity testing and adulteration screening; in R&D it functions as a sesquiterpene scaffold for chemical derivatization (e.g., oxidations, hydrogenations) and as a reference compound in studies of in vitro antimicrobial/antioxidant properties and the sensorial impact of woody components; additionally, some aromatherapy and air-care formulations leverage guaiene as a warm woody note to balance citrus–floral accords, typically at low dosage in line with contemporary fragrance safety guidance.
