Abstract
A method for determining an amount of teriflunomide in a sample by mass spectrometry includes adding an internal standard to the sample, subjecting the sample to solid phase extraction, purifying the sample by high turbulence liquid chromatography, ionizing the sample to produce one or more teriflunomide ions detectable by mass spectrometry, determining the amount of the one or more teriflunomide ions by mass spectrometry, and using the amount of the one or more ions determined to further determine the amount of teriflunomide in the sample.
