Polymorphism analysis of pharmaceutical raw materials is considered one of the most relevant evaluations that should be done. As we know, different crystal forms from the same molecule have differences in terms of their ...

A simple, fast, and sensitive HPLC method with UV detection has been developed for the quantitation of ursodeoxycholic acid (UDCA) in raw material and pharmaceutical formulation (suspension). Cromatographic conditions were: ...

Abstract: Objective: To develop a highly sensitive LC-MS/MS (liquid chromatography-mass spectrometry/mass spectrometry)method applied to the detection and quantitation of UDCA (ursodeoxycholic acid) related substances such ...

The determination of the spatial configuration of the compounds structures used in the production of drugs is of utmost importance due to the different physical characteristics that each have in their solid state and ...

In this work we studied qualitative methods for analysis and identification of cefazolin sodium, β-lactam antimicrobial for parenteral use, belonging to the group of first-generation cephalosporin, used as a therapeutic ...

A simple, sensitive and stability indicative method for the simultaneous quantification of ethionamide (ETA) in raw material and pharmaceutical dosage forms by high performance liquid chromatography (HPLC) was developed. ...
