  • Applications

    3-N-Butyl-4,5-dihydrophthalide (CAS 62006-39-7) is a phthalide occurring in essential oils of celery (Apium graveolens) and Chuanxiong (Ligusticum chuanxiong), widely used in neuropharmacology and cerebrovascular research as a reference standard, quality marker, and bioactive comparator; it has been investigated for anti-ischemic, neuroprotective, antiplatelet, antioxidant, and anti-inflammatory effects, enabling mechanistic studies on cerebral microcirculation, mitochondrial function, and Nrf2/NF-κB signaling; it serves as a scaffold/lead for derivative design and for delivery/formulation work (microemulsions, nanosystems, liposomes) to improve solubility and bioavailability; in botanical and analytical contexts it is a marker compound for celery- and chuanxiong-derived extracts, supporting HPLC/GC-MS method development and stability assessment; it also finds value in flavor and fragrance as a celery-like aroma component and in agro/microbiology as a candidate with antibacterial or insect-related activities, while any direct clinical or food uses remain subject to rigorous safety evaluation and jurisdiction-specific regulation.
