10 and 2.67 μg/ml, respectively. The proposed method met all criteria for validation in accordance with the International Conference on harmonization (ICH) guidelines. The presented work monitored the degradation profile for VEC under various stress conditions and provided a simple LC method for its routine analysis. The structures of the forced degradation products had been described in details using the MS data and the possible degradation pathways were outlined. Besides, the results obtained from the developed met
