CAS:Benzopurpurin 4B is a cationic surfactant that is used as an optical sensor for copper ions. It can be used to detect and quantify the presence of copper ions in solution. Benzopurpurin 4B is not soluble in water, but it does dissolve in organic solvents such as cyclohexane or chloroform. Benzopurpurin 4B has been shown to bind to amines and polyvinyl chloride surfaces and exhibit a fluorescent response when exposed to radiation. The uptake of benzopurpurin 4B by cells has been observed using a confocal microscope, showing that it binds to the hydroxyl groups on proteins.
