Cyprotex kinetic solubility
WebAug 1, 2011 · The high ionic strength of the pH 7.4, 0.1 M phosphate buffer provides good buffering capacity for highly soluble compounds that are readily ionized in solution. The use of such a buffer can result in basic compounds, when present at high concentrations, precipitating out as a phosphate salt. WebKinetic solubility has two distinguishing characteristics: (a) the compound initiall y is full y dissolv ed in an or ganic solv ent (e.g., DMSO) then ad ded to the aqueous b uffer and (b) equili-brium is not reached between dissolved compound and solid compound. Here using the basic conce pt of kinetic solubility ,
