Fluorescent Brightener 220, Technical grade

CAS: 16470-24-9

Fluorescent Brightener 220, Technical grade (FB220) is a fluorescent compound that confers a bright green fluorescence in the visible spectrum upon irradiation with ultraviolet light. FB220 is used as an additive in detergent compositions for detection of soil and stains on fabrics. It also has been used as a fluorophore to monitor the progress of chemical reactions, to detect bacteria in agrochemical testing, and to measure the time required for various compounds to diffuse through microcapsules. The fluorescence intensity of FB220 can be decreased by cationic surfactants and fatty acid compounds.
Fluorescent Brightener 220 can be inhibited by certain drugs such as phenobarbital, phenytoin, carbamazepine, and primidone.
