| Abstract: | A capillary gas chromatographic method for the determination of dimethyl fumarate in the mdd inhibitor was developed and butenoic acid was selected as the internal standard substance.The samples were extracted with ethyl acetate and then analyzed by DM-FFAP capillary gas chromatography with FID.The dimethyl fumarate and butenoic acid were separated from each other within 3 minutes.The calibration curve was linear over a range from 0.25 to 3.0 mg/mL with a correlation coefficient of 0.9996 and the detection limit was 5.0 mg/mL.The recoveries for spiked standards were between 97.0% and 104.4% and the relative standard deviation was 3.26%.The method presented the advantages of simple pretreatment and high precision.The method can be used to test the dimethyl fumarate in the mold inhibitor. |
