What is BCIM CAS 7189-82-4？
BCIM is usually hexaaryldiimidazole, which can be prepared by polymerization of triphenylimidazole. It has a large conjugated system and two imidazole units, exhibiting good fluorescence properties and can be used as a photoinitiator in organic photochemical reactions. Hexaaryldiimidazole is a type of organic compound (HABI), typically hexaphenyldiimidazole.

Application
2,2 ‘- di (2-chlorophenyl) -4,4’5,5’ – tetraphenyl-1,2 ‘- diimidazole is a photoinitiator called o-chlorohexaaryldiimidazole (BCIM). The current synthesis method uses sodium hypochlorite as the oxidative condensing agent for BCIM, which brings a lot of alkaline “wastewater” and has low yield and high cost.
Packaging
Usually packed in 25kg/drum,and also can be do customized package.
