Product Name:2,2'-Bis(2-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole
English Name:2,2'-Bis(2-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole
CAS No.:7189-82-4
Aliases:2,2'-Bis(2-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole, Tetraphenyl biimidazole, HABI
Molecular Formula:C42H28Cl2N4
Physical Properties:White to light yellow crystalline powder, insoluble in water, easily soluble in organic solvents such as benzene, toluene, and ethyl acetate. It undergoes homolytic cleavage under UV irradiation to generate free radicals. Melting point approximately 200°C with good thermal stability.
Uses:Used as a photoinitiator to generate free radicals upon UV irradiation, initiating polymerization of monomers such as acrylates. Suitable for UV-curable coatings, inks, photoresists, and holographic recording materials, especially in high-sensitivity polymerization initiating systems.
Technical Specifications:
White to light yellow crystalline powder
Content (HPLC) ≥98.0%
Melting point 200~210°C
Loss on drying ≤0.5%
Solubility: Soluble in toluene, ethyl acetate and other organic solvents, insoluble in water
