| titleOfInvention | Method for simultaneously determining various related substances of montelukast sodium and preparation thereof |
| abstract | The invention relates to the technical field of analytical chemistry, in particular to a method for simultaneously measuring montelukast and a plurality of related substances. HPLC determination is adopted, and phenyl bonded silica gel is used as a chromatographic column of the filler; gradient elution was carried out using 0.15% trifluoroacetic acid aqueous solution (a) to 0.15% trifluoroacetic acid acetonitrile solution (B) as a mobile phase. The detection wavelength is 250-260 nm, and the column temperature is 38-42 ℃; the elution flow rate is 1.0-2.0 mL/min. The method is simple and convenient to operate, and can be used for quickly, effectively and accurately measuring the content of the montelukast and various related substances. |
