Description

Ligustilide (CAS No. 4431-01-0) is a bioactive phthalide derivative with the molecular formula C₁₂H₁₄O₂. This compound is a key constituent found in traditional Chinese medicinal herbs such as Angelica sinensis and Ligusticum chuanxiong, renowned for its pharmacological properties. Ligustilide exists in both cis (Z-ligustilide) and trans (E-ligustilide) isomeric forms, with the Z-isomer being the predominant and more biologically active form. It is characterized by a butylidene side chain fused to a dihydroisobenzofuranone core, contributing to its unique chemical and therapeutic profile.

Our high-purity Ligustilide (≥98% by HPLC) is rigorously tested for quality, ensuring optimal performance in research applications. It is supplied as a light-yellow to colorless viscous liquid or crystalline solid, soluble in organic solvents such as DMSO, ethanol, and acetonitrile. Store at -20°C under inert conditions to maintain stability. Ideal for pharmacological, phytochemical, and biochemical studies investigating anti-inflammatory, neuroprotective, and vasodilatory mechanisms.
