Coumarins are a group of plant-derived polyphenolic compounds. They belong to the benzopyrones family and possess a wide range of pharmaceutical applications including cytoprotective and modulatory functions, which may be translated into therapeutic potential for multiple diseases. Several natural and synthetic coumarins and derivatives, such as coumarin glycosides, possess potent biological activities. Coumarin derivatives are found in antibiotic, antimitotic, immunomodulating, antiviral, anticancer, anti-inflammatory, anticoagulant, antifungal, antioxidant, and cytotoxic agents, as well as some biological assays.

Coumarins have additional industrial applications. The fluorescence of coumarins, such as 7-hydroxycoumarin, is widely used as a research tool in polymer science. Coumarins are used as laser dye-sensitized photoinitiators, for incorporation into polymer chains by co-polymerization, in the estimation of polymer solvent effects, for various structural characterizations, in the monitoring of the releasing properties of poly(methylmethacrylate) nanospheres and for polymeric fluorescent solar collectors. The presence of a halogen allows these reagents to be used as substrates in various coupling reactions, including Suzuki-Miyaura cross-coupling reactions.
