Abstract

The invention belongs to the field of analytical chemistry, and particularly relates to a detection method of related substances of moxifloxacin hydrochloride. Phenyl bonding silica gel is selected and used as a chromatographic column of a filler, and the mixed solvent gradient elution of a buffer and an organic phase is used as mobile phases for detection. The method realizes effective separationon 16 types of impurities of the moxifloxacin hydrochloride under the same chromatographic column condition through improvement on technology of the chromatographic column, elution gradients, columntemperature and the like. The method is good in stability, has good specificity, is high in sensitivity, and is high in resolution.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to a method for detecting related substances of moxifloxacin hydrochloride. Background technique [0002] Moxifloxacin hydrochloride (Moxifloxacin hydrochloride), chemical name: 1-cyclopropyl-6-fluoro-7-((4aS,7aS)-1H- [0003] [3,4-b]hexahydropyridodihydropyrrole-6(2H))-8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylate hydrochloride, the structural formula is as follows : [0004] [0005] Moxifloxacin hydrochloride is an extended-spectrum quinolone antibiotic developed by Bayer Pharmaceutical Company of Germany. It was first launched in Germany in September 1999 and was approved by FDA in December of the same year. Moxifloxacin hydrochloride is an 8-methoxyfluoroquinolone antibacterial drug with broad-spectrum antibacterial activity and strong bactericidal effect. It is effective against Gram-positive bacteria, Gram-negative bacteria, anaerobic bacteria, acid-f...
