Diazepam solubility in methanol
WebThe solubility of diazepam in the LVPs ranged from 0.04 to 0.05 mg/ml at 25 degrees C. The effects of solution dielectric constants on nonelectrolyte solubility and the minimal fraction of protonated (ionized) diazepam present in typical admixtures are deduced to be negligible determinants of diazepam solubility in i.v. solutions at pH greater ...
