Embodiment 1

[0079] Preparation of system suitability solution:

[0080] Dissolve the sugammadex sodium sample and impurities 1-20 in the same solvent as mobile phase A to obtain a mixed solution, wherein the concentration of sugammadex sodium in the mixed solution is 5 mg / ml, and the concentration of impurities 1-20 5 μg / ml respectively.

[0081] The system suitability solution is injected into the liquid chromatograph, wherein the chromatographic conditions are:

[0082] Column: C 18 Chromatographic column (YMC ODS-AQ 150×4.6mm, 3μm);

[0083] Mobile phase A: configure 20mmol / L potassium dihydrogen phosphate solution, and adjust the pH value to 2.3 with phosphoric acid;

[0084] Mobile phase B: acetonitrile;

[0085] UV detection wavelength: 200nm;

[0086] Flow rate: 0.8ml / min

[0087] Column temperature: 40°C;

[0088] Gradient elution program:

Abstract

The invention relates to a method for detecting sugammadex sodium, which comprises the following steps of: respectively detecting a test sample solution and a reference substance solution by using a high performance liquid chromatograph under the chromatographic conditions that: a chromatographic column is a C18 chromatographic column; a mobile phase A is a phosphate buffer solution with the concentration of 5 mmol / L to 40 mmol / L or a phosphoric acid aqueous solution with the volume concentration of 0.1 percent to 1.0 percent, and the pH value of the mobile phase A is 2.0 to 2.9; a mobile phase B is acetonitrile; the column temperature of the chromatographic column is 30-45 DEG C; the flow rate is 0.6 ml / min to 1.2 ml / min; and the wavelength of the ultraviolet detection is 190 nm to 210 nm. According to the detection method of sugammadex sodium provided by the invention, sugammadex sodium related substances can be effectively separated, the sensitivity is high, the specificity is good,and the accuracy is high.

Description

technical field [0001] The invention relates to the field of analytical chemistry, in particular to a method for detecting sugammadex sodium. Background technique [0002] Sugammadex Sodium or Sugammadex was first developed by Organon Biosciences. In 2007, Organon was acquired by Schering-Plough, and in 2009, Schering-Plough merged with Merck. Sugammadex sodium is currently owned and sold by Merck, and has become a medium-sized product under Merck. In 2008, Sugammadex Sodium was launched in Europe for the first time, and then in Japan, the United States and other countries, and is now on the market in 75 countries. In 2016, Merck proposed the listing of Sugammadex Sodium in China. [0003] Sugammadex sodium is a modified γ-cyclodextrin, the first and only selective muscle relaxation antagonist (binding agent) (SRBA) successfully developed in 20 years, which encapsulates Aminosteroid non-depolarizing muscle relaxants block the relaxation effect, can quickly and predictably ...
