Stability
Guanidine Phosphate is a white crystalline powder exhibiting high solubility in water, dissolving at a rate of 15.5 g per 100 g at 20°C, or 250 g/L. It shows limited solubility in methanol and is practically insoluble in non-polar organic solvents such as benzene, acetone, and diethyl ether. It is primarily used to adjust and stabilize the pH of solutions.
