  • Applications

    Viridiflorene (CAS 21747-46-6) is a sesquiterpene hydrocarbon occurring in plant essential oils; in practice it is used chiefly as a reference/standard in GC-MS/GC-FID for qualitative and quantitative analysis and quality control of essential oils, flavors, and herbal materials; as a fragrance contributor imparting woody, resinous, green nuances in perfumery, cosmetics, and personal care; as a model compound for biological and chemical research (terpene biosynthesis, metabolism, chemical ecology) and for optimizing extraction and purification processes; it is also investigated for antimicrobial, antioxidant, and insect-repellent properties to guide potential uses in preservation, agriculture, and bio-based materials; and serves as a chemical marker for chemotaxonomy, provenance tracing, assessment of geographic/seasonal variability, and as a volatility/odor marker in sensory and aroma dispersion studies.
