I have a technical question, I need to know how to prepare a BCS stock solution, is it soluble in water? To prepare the stock solution, need I buy the compost as a Bathocuproinedisulfonic acid disodium salt hydrate?
Dear Damaris Lorenzo , yes, the bathocuproinedisulfonic acid disodium salt seems to be the best choice. On the Sigma Aldrich page (see link below) the solubility of this reagents in water is given as 50 mg / mL.
