Description

Application

• beta-lactoglobulin stabilized nanemulsions--Formulation and process factors affecting droplet size and nanoemulsion stability.: This study investigates the impact of formulation and process parameters on the stability and size of beta-lactoglobulin stabilized nanemulsions, potentially involving potassium phosphate dibasic in the formulation process (Ali et al., 2016).


• Correlation of characteristics of gel extrusion module (GEM) tablet formulation and drug dissolution rate.: Examines how the characteristics of gel extrusion in tablet formulations influence drug dissolution rates, relevant for chemists looking into dissolution behavior and possibly involving potassium phosphate dibasic (Juang and Storey, 2003).


• High-performance liquid chromatographic determination of phenylureas by photochemically-induced fluorescence detection.: Discusses a method for detecting phenylureas using high-performance liquid chromatography, which could involve potassium phosphate dibasic as a component of the mobile phase or sample preparation (Munoz de la Pena et al., 2002).


• Assay and purity analysis of diatrizoate sodium in drug product by LC.: This research details a method for assaying and analyzing the purity of diatrizoate sodium, where potassium phosphate dibasic could be part of the chromatographic system (Chellquist et al., 1997).
