Development and validation of stability-indicating assay method and identification of force degradation products of glucagon-like peptide-1 synthetic analog Exenatide using liquid chromatography coupled with Orbitrap mass spectrometer.

Exenatide is a synthetic glucagon-like peptide 1 analog, widely used in the management of type 2 diabetes mellitus. The stability of pharmaceutical products is significantly impacted by various environmental stress conditions. The present study reports the development of a validated reverse-phase high-performance liquid chromatography (RP-HPLC) stability-indicating method for the identification of force degradation products (DPs) of synthetic glucagon-like peptide-1 analog Exenatide using UHPLC-Orbitrap fusion mass spectrometer.
