Coumarin

Coumarin dyes are a class of fluorescent compounds with coumarin as the parent core, which have good photostability and high quantum yield. They have a wide range of excitation and emission wavelengths and are suitable for multicolor fluorescent labeling. They are often used in the detection and imaging of biological molecules such as nucleic acids and proteins, as well as in the fields of fluorescent probes, sensors and drug tracers.
