Description

Isoimperatorin CAS NO 482-45-1 is a naturally occurring furanocoumarin compound, a key bioactive constituent found in several medicinal plants such as *Angelica dahurica* and *Cnidium monnieri*. This high-purity phytochemical is valued for its significant pharmacological potential and serves as a critical reference standard and active ingredient. It is essential for research and development in the pharmaceutical, nutraceutical, and cosmetic industries, where precise quality and reliable sourcing are paramount for product efficacy and safety.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and standardization of herbal extracts and finished products in pharmacopoeial testing.
• Active Pharmaceutical Ingredient (API) Intermediate: Serves as a key starting material or intermediate in the synthesis of novel drug candidates targeting inflammation, cancer, and skin conditions.
• Nutraceutical Formulations: Incorporated into dietary supplements for its potential antioxidant and health-promoting properties, requiring high-purity botanical extracts.
• Cosmetic & Skincare Actives: Used in premium cosmetic formulations for its purported photoprotective and skin-brightening effects.
• Biochemical & Life Science Research: Employed in academic and industrial laboratories to study furanocoumarin bioactivity, metabolism, and mechanism of action.
• Herbal Extract Standardization: Critical for calibrating analytical equipment (HPLC, LC-MS) to ensure batch-to-batch consistency and potency of commercial botanical extracts.
