Description of key information

According to preliminary water solubility tests and analytic report, CuGUN is dissociated in water at pH 4, 7 and 9, and  lead to the formation of copper (ion) and N-guanylurea. These two products are stable and therefore, they are used to follow up the concentration of CuGUN in the different media. CuGUN is a substance which is stable according to analytical report at pH under 4 and remaining as a complex to form a visible suspension.

Key value for chemical safety assessment
