    Gurjunene (unknown isomer, CAS 80599-13-9) is a sesquiterpene hydrocarbon found in various essential oils and is applied primarily as a fragrance ingredient in perfumery, flavor and personal care, valued for its warm woody–balsamic character and its role as a blender/nuance modifier; it is also used in fragranced home-care products (candles, air care, scented cleaners) and as an analytical reference in GC/GC–MS for terpene identification/quantification, spectral library building and support for retention index assignments, isomer-resolution studies, and investigations of oxidative/aging stability and packaging effects on odor; in R&D, gurjunene can serve as a hydrocarbon scaffold for mild functionalization and derivative generation, for testing perceived longevity and bloom, for essential-oil quality control and traceability (chemical fingerprinting and adulteration checks), and it is explored at in vitro/preclinical screening level for typical sesquiterpene properties (e.g., antimicrobial, antioxidant) without implying efficacy, with practical use guided by applicable safety and regulatory frameworks (e.g., IFRA/local) and product-specific irritation/sensitization testing.
