A simple strategy for washing a recrystallized drug from viscous and non-volatile solvents prior to XRD study: A technical note

Abstract

Aim: obtaining a dried powder residual from a viscous and non-volatile solvents isimpossible. Thus, their analysis by using the methods required for the dried formof materials has always been a problem. In the current technical note, our aim wasto offer a simple method for this issue. Results: the proposed method was basedon washing of the viscous residuals with a volatile solvent and their drying in theambient conditions. For this purpose, we have provided sufficient data on somedrugs in the selected viscous and non-volatile solvents to support our claim.
