Determination of impurities in the starting material of Prucalopride succinate by GC
OBJECTIVE To control the impurities in 1-(3-methoxypropyl)-4-piperidine from the starting material of Prucalopride succinate.METHODS The sample was analyzed by Gas chromatography using the CP-Sil8CB capillary column of(5%)phenyl-(95%)dimethyl polysiloxane(30 m × 0.25 mm,0.5 µm)as the analytical column.The carrier gas was N2,and the gasification chamber temperature was 280 ℃.The column temperature was 150 ℃ with the detector temperature of 280 ℃,the carrier gas flow was 1.0 mL·min-1,the split ratio was 100:1,and the injection volume was 1 μL.RESULTS The linear range of impurity A was 0.083-0.825 mg·mL-1(r2=0.9971).The average recovery was 109.8%,RSD=2.24%.The linear range of impurity B was 0.08-0.841 mg·mL-1(r2=0.9998),and the average recovery was 102.9%,RSD=2.03%.CONCLUSION The method used can effectively control the impurities A and B in 1-(3-methoxypropyl)-4-piperidinamine to obtain high purity Prucalopride succinate.
