Abstract

The invention discloses a tigecycline intermediate analysis detection method used for tigecycline intermediate quality control, a chromatographic column with octadecylsilane chemically bonded silica as a packing is used for high performance liquid chromatography analysis detection at the column temperature of 25-35 DEG C in the flow rate of 0.6-1.2mL / min with the detection wavelength of 245nm, wherein the pH value of the mobile phase is adjusted to 6.80-7.20 with 10% ammonia. The tigecycline intermediate analysis detection method selects an ordinary chromatographic column and a liquid chromatographic system, has the advantages of low price, high practicability and simple operation, can effectively separate a tigecycline intermediate from impurities.

Description

technical field [0001] The invention relates to a high-performance liquid chromatography analysis method, in particular to an analysis and detection method for a tigecycline intermediate. Background technique [0002] Tigecycline was researched and developed by Wyeth Corporation of the United States. It is the first glycylcycline antibiotic approved for clinical intravenous administration. Its mechanism of action is similar to that of tetracycline antibiotics, both through binding to bacterial ribosomes , to prevent the entry of transfer RNA, so that amino acids cannot be combined with peptide chains, and finally play a role in blocking bacterial protein synthesis and limiting bacterial growth, but the binding ability of tigecycline to ribosomes is 5 times that of other tetracyclines. [0003] 9-aminominocycline hydrochloride is an important intermediate for the synthesis of tigecycline, and its chemical formula is C 23 h 28 N 4 o 7 HCl, the structural formula is: [00...
