Products Description
CAS 1041-00-5 is a bis-benzoxazole derivative that is insoluble in water but soluble in ethanol and dimethylformamide. It demonstrates strong resistance to light, chlorine bleaching, hard water, and acids (pH 2 to 3), as well as alkalis (up to pH 10) without significant degradation.
This compound has a maximum absorption wavelength of approximately 353 nm, contributing to its fluorescence properties. It is used as a fluorescent whitening agent in textiles and plastics, enhancing their appearance by absorbing ultraviolet light and emitting blue fluorescence, making materials appear whiter and brighter.
