  • Applications

    Liquiritin (CAS 551-15-5) is a flavonoid glycoside derived from Glycyrrhiza species (licorice). In industry it is primarily used as an analytical reference standard for quantifying licorice-derived flavonoids in pharmaceutical and botanical products by HPLC/LC-MS. It also serves as a chemical intermediate in flavonoid synthesis and in formulation development for research and product development projects, including licorice-derived ingredients used in cosmetics and personal-care formulations. Occasional exploration in flavor and fragrance contexts considers licorice-related flavonoids for flavor systems and aroma profiles. Additionally, liquiritin-containing extracts are encountered in some nutraceuticals and botanical preparations, where its presence supports raw-material quality control. Use is subject to local regulations and formulation limits.
