  • Applications

    trans‑β‑Bergamotene (CAS 15438‑94‑5) is used as a fragrance ingredient in fine fragrance, cosmetics, and household fragranced products (imparting warm woody, herbal, slightly citrus‑spicy nuances that round and reinforce citrus, woody, and spicy accords), in essential‑oil‑derived flavor formulations, and as a GC–MS reference/standard to identify and quantify volatile profiles of essential oils, agricultural materials, and botanical terpene chemotypes; in chemical‑ecology and pest‑management research it functions as a semiochemical that mimics plant volatiles to study insect behavior, attract natural enemies, and develop bio‑lures; it also serves as a model/building block for terpene synthesis and metabolic engineering to generate new sesquiterpene libraries, and is explored for potential bioactivities (e.g., antimicrobial, antioxidant) for discovery purposes without therapeutic claims.
