Fluorescent Brightener 251

CAS: 16324-27-9

Fluorescent Brightener 251 is a quaternary ammonium salt that is used as a fluorescent whitening agent. It has been shown to be safe for use with human keratin and can be identified by its ultraviolet-visible spectra. This compound is a polybasic, anionic compound that is neutralized with a diluent and then chloride. The radiation emitted by the compound triggers the emission of visible light, which is what makes it fluorescent. Fluorescent Brightener 251 emits radiation in three wavelengths: 280 nm, 350 nm, and 420 nm. The evaporation rate of this compound depends on the counterions present in the solution. Fluorescent Brightener 251 undergoes a stepwise reaction with reactive compounds.
