Background:
6,8-Difluoro-7-hydroxy-4-methylcoumarin is a fluorophore.1It has been conjugated to streptavidin or secondary antibodies for flow cytometry and used to label bacteria for multi-color fluorescencein situhybridization (FISH).2,16,8-Difluoro-7-hydroxy-4-methylcoumarin has also been coupled to peptides to improve electrospray ionization and MS sensitivity in MALDI-TOF MS.3It displays absorption/emission maxima of 358/455 nm, respectively.4
