Development of a stability-indicating HPLC method of Etifoxine with characterization of degradation products by LC-MS/TOF, 1H and 13C NMR

- There are no real analytical methods for Etifoxine in the literature.
- The optimal stability-indicating RP-HPLC conditions are performed.
- Four degradation products obtained by different stress are characterized by LC-MS/TOF and 1H and 13C NMR.
- The selected method is completely validated for Etifoxine and its four degradation products.
