Definition:A hydroxycoumarin that is 4-methylcuomarin which is substituted by hydroxy groups at positions 3 and 4. A hyaluronan synthesis inhibitor. It has also been used as a fluorescent sensor to monitor the consumption of a boronic acid in Suzuki coupling reactions; fluorescence is readily detectable by the naked eye using a standard 365 nm UV lamp.
