Application

Umbelliferone can be used:
  • To synthesize fluorescent probes to detect cyanide anions in water at biological pH and for in vitro and in vivo detection of hydrogen peroxide.
  • In the preparation of coumarin-based polymer as optical data storage material.
  • As a precursor to synthesize novobiocin derivatives that exhibit antibacterial agents as well as inhibitors of DNA gyrase.
  • As the starting material to synthesize (+)-decursinol and (+)-angelmarin.
