Product Name: Fluorescent brightener OB-1

Chemical Name: Fluorescent brightener OB-1

Synonyms: 2,2'-(Vinylenedi-p-phenylene)bisbenzoxazole

CAS No: 1533-45-5

EINECS No: 216-245-3

Appearance: Green yellow crystalline powder

Properties: Does not dissolve in water, can dissolve in such high boiling point solvents as trichlorobenzene, diphenyl ether, etc. ; Because this product has high melting point and strong stability, so it has very good heat resistance; Because this product's hydrophobic nature, so it has good light fastness; and for it has strong fluorescence, it can not only improve the whiteness of the products but also can improve the brightness, so it can be used as disperse dyes in the chemical fibre, can be used like oil dissolving coloring agent in the plastics.
