  • Applications

    Acorone (CAS 10121-28-5) is a natural constituent reported in Acorus essential oils and is commonly used as an analytical reference for GC–MS/LC–MS in qualitative/quantitative profiling, as a comparator in herbal quality control, and as a chemical fingerprint marker for raw‑material authentication; it is also explored as a lead/intermediate scaffold in medicinal and biochemical research to probe putative bioactivities (e.g., antimicrobial, antioxidant, neuromodulatory) at preclinical levels, enabling screening and structure–activity modeling; in flavor and fragrance R&D, Acorone may be evaluated as a warm, herbal note to build accords and assess aroma stability across formulation matrices; additionally, it supports extraction/process optimization, QC standardization, method development (SPE, microextraction, internal standardization), and laboratory training; all uses should follow safety practices, toxicological assessment, and MSDS guidance, and comply with local regulatory requirements.
