A polarimetry method was developed for the determination of S-2-(aminomethyl)-1-ethylpyrrolidine.At(20±0.5)℃,the optical rotation of S-2-(aminomethyl)-1-ethylpyrrolidine was determined with ethanol as the solvent at 589.3 nm wavelength.In the concentration range of 0.02~0.05 g/mL,the following linear regression equation,a=-0.936 9c-0.031 1(r=1.000),was established,and the average recovery was 99.84%,and the RSD was 0.23%(n=4).The method is accurate,simple,fast,stable and credible,and it can be used for the quality control of S-2-(aminomethyl)-1-ethylpy-rrolidine.
