Problems solved by technology

[0004] ChP is detected by high-performance liquid chromatography system, in which citrate buffer-acetonitrile isocratic elution is used. This method has more salt phases, and ion-pairing reagents are used at the same time, which will cause greater damage to the chromatographic column, and the sensitivity is too low. 0.1% impurity cannot be detected
[0005] The BP method and EP9.0 method are the same as the USP41 method. They all adopt high-performance liquid chromatography system, in which 0.05% trifluoroacetic acid and acetonitrile are used for gradient elution, and trifluoroacetic acid has great damage to the chromatographic column. The degree of separation from each impurity does not meet the requirements

Abstract

The invention relates to the technical field of drug quality detection, and provides a method for detecting related substances of aripiprazole. The invention uses reversed-phase high-performance liquid chromatography for detection, and calculates the content of related substances of aripiprazole through self-control method ; The detection method provided by the invention prepares each solution with methanol-acetonitrile-water-glacial acetic acid mixed solvent, and the blank solvent will not interfere with the determination of related substances; use potassium dihydrogen phosphate buffer solution-methanol-acetonitrile as mobile phase to carry out gradient elution , Potassium dihydrogen phosphate is less dangerous, it is convenient for experimenters to operate, the mobile phase is easy to obtain and has less damage to the chromatographic column, and good separation can be achieved between impurities and between impurities and main components; the detection method provided by the invention is exclusively Good performance, good durability, can accurately detect the known impurities of aripiprazole, and the resolution of each peak, the number of theoretical plates and the tailing factor are all good. Compared with the current pharmacopoeia method, it can detect the related substances of aripiprazole more conveniently and quickly.

Description

technical field [0001] The invention relates to the technical field of drug quality detection, in particular to a method for detecting related substances of aripiprazole. Background technique [0002] Aripiprazole is a new type of atypical antischizophrenia drug, which has a bidirectional regulation effect on the DA nervous system and is a stabilizer of DA transmitters. It has high affinity with D2, D3, 5-HT1A and 5-HT2A receptors. It produces anti-schizophrenia effect through partial agonism on D2 and 5-HT1A receptors and antagonism on 5-HT2A receptors. [0003] Combined with the synthesis process of aripiprazole, it can be known that the following impurities (ie related substances of aripiprazole) usually exist in aripiprazole: aripiprazole impurity A, impurity B, impurity C, impurity D, impurity E, impurity F, Impurity G, isomer impurities and intermediate impurities. ChP (Chinese Pharmacopoeia), USP (United States Pharmacopoeia), BP (British Pharmacopoeia) and EP (Eur...
