water 1.2 0.8 1.0 2.1 N F OH OH F O monovalent week acid below pH 7: unionized SpH = So Management insisted on the measurement! Purchasing considerations include the solubility testing method desired (e.g., solubility measurements per Bjerrum analysis), existing liquid-handling equipment, bench space, operator training, and the need to measure drug solubility in specific conditions, such as in the presence of certain excipients. Excellent Good Average Bad Terrible 0 Comments. Moderator. Select All. The chapter also briefly describes typical experimental methods used to assess solubility determination of pharmaceutical materials. This chapter provides an overview of the concepts and equations that are relevant to solubility measurements. The potentiometric acid–base titration for the solubility measurements is based on a characteristic shift in the middle of the titration curve that is caused by precipitation. <1236> Solubility Measurements April 24, 2017 Confidentiality Label 3 <1724> Semisolid Drug Products - Performance Tests April 24, 2017 Confidentiality Label 4. Solubility shall be determined in a step-wise procedure that involves attempting to dissolve a test chemical in the solvents (in the order of preference) at relatively high concentrations using the sequence of mechanical procedures (Section VII.C.2.a). - 37°c to support biopharmaceutical evaluation.
