  • Applications

    Phellopterin, CAS 2543-94-4, is primarily used as an intermediate and building block for the synthesis of furanocoumarin derivatives in pharmaceutical and natural product chemistry research; it serves as an intermediate in synthetic routes to related furanocoumarins. In analytical chemistry, it is frequently employed as a reference standard to develop and validate LC/UV and LC-MS methods for organic heterocycles and natural products. Additionally, it is studied for its photochemical and photophysical properties, supporting assessments of light-driven behavior and potential use in photoactive materials or light-activated processes. These applications reflect its role as a synthetic intermediate, analytical reference material, and a research reagent with relevance to natural products and materials science, subject to local regulations and formulation limits.
