Dexamethasone HPLC Assay and Impurity Profiling Methods Following United States Pharmacopeia Monograph Guidelines Using a Titan C18 Column and UV Detection

A simple, precise and sensitive Reverse-Phase High Pressure Liquid Chromatography gradient method was adapted for traceability, homogeneity and total chromatographic analysis of Dexamethasone. The given experimental conditions follow the USP43-NF38 monograph method for Dexamethasone Assay and Organic Impurity Profiling. Dexamethasone, Betamethasone, Dexamethasone acetate and Desoximetasone were baseline resolved within 20 minutes using a Titan C18 UHPLC column (2.1 x 100 mm, 1.9 µm).
