I have to use this chemical probe for OH radical detection in water and due to its low solubility, I'm finding difficulty. Please suggest to me any other solvent or anyway by which I can use it according to my requirement.
I tried making a concentrated Coumarin solution in Ethanol and then using it made the required aqueous Coumarin solution. I got a very good solubility by this method in both Ethanol and water. The only problem now is I am getting variable results in my further experiment.
