Abstract

The invention relates to a method for detecting lurasidone by using ultra-high performance liquid chromatography-tandem mass spectrometry. The method comprises the following steps: (1), putting a sample to be detected into a volumetric flask, adding acetonitrile-water (3-9): 2 to fix the volume to 10-50 ml, carrying out vortex mixing for 7-13 min, carrying out ultrasonic extraction for 7-13 min, passing through a 0.22 [mu]m filter membrane, and injecting the sample to detect lurasidone in the sample; and (2) detecting the lurasidone by adopting an ultra-high performance liquid chromatograph-tandem mass spectrometer (UPLC-MS / MS) as a detection instrument. The detection method has the advantages of good selectivity, high sensitivity, simplicity, rapidness and the like. By using UPLC-MS / MS, the lurasidone in bulk drugs, pharmaceutical preparations and other samples can be rapidly and efficiently tested in a limited manner; and the detection sensitivity of the lurasidone can be effectively improved, matrix interference is effectively avoided, and the detection limit of the lurasidone is reduced.

Description

technical field [0001] The invention relates to the application field of high-performance liquid chromatography technology, in particular to a method for detecting lurasidone by using ultra-high performance liquid chromatography-tandem mass spectrometry. Background technique [0002] Lurasidone hydrochloride (lurasidone hydrochloride) is a novel antipsychotic drug with dual effects developed by Sumitomo Pharmaceutical Co., Ltd. of Japan. 2A receptors and dopamine D 2 The receptors all have high affinity and have significant curative effect on both positive and negative symptoms of psychotic patients. [0003] During the synthesis of lurasidone hydrochloride, the incomplete removal of impurities in its intermediates will cause side reactions and the generation of impurities, thereby affecting the purity and quality of the drug. Therefore, realizing the separation and determination of lurasidone hydrochloride intermediates and related substances can ensure the purity of reac...
