Abstract

The invention relates to the technical field of analytical chemistry and discloses a method for detecting afatinib-dimaleate-related substances through high performance liquid chromatography. According to the method, an afatinib dimaleate raw material drug or preparation is prepared into a detection solution with diluents, octadecyl silane keys and silica gel serve as fixing phases, inorganic salt buffer liquid is adopted as a flowing phase A, an organic phase serves as a flowing phase B, gradient elution is conducted, and an HPLC spectrogram is recorded under afatinib absorption wave length. According to the method, a chromatographic column with the octadecyl silane keys and silica gel serving as filler is adopted, the inorganic salt buffering liquid-organic phase for regulating the proper pH value serves as the flowing phase, the contents of related substances existing possibly of the afatinib dimaleate and a preparation thereof can be measured quantitatively, main impurities and various impurities can be completely separated, the peak pattern is good, regulations of Chinese pharmacopoeia are satisfied, the quality of the afatinib dimaleate and a preparation product containing the afatinib dimaleate is effectively controlled, and the method is high in specificity, high in sensitivity and good in accuracy.

Description

technical field [0001] The invention relates to the technical field of analytical chemistry, in particular to a method for detecting related substances of afatinib maleate by using high performance liquid chromatography. Background technique [0002] Afatinib maleate is an irreversible ErbB family blocker, which can selectively and effectively block the signal transduction of ErbB family receptors (EGFR, HER2 [ErbB2] and ErbB4) and block the relationship between cancer cell growth and Split related main channels. For the first-line treatment of advanced non-small cell lung cancer (NSCLC) and HER2-positive advanced breast cancer patients (for the treatment of non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations). [0003] Afatinib maleate chemical name: 4-Dimethylamino-but-2(E)-enoic acid [4-(3-chloro-4-fluoroanilino)-7-(tetrahydrofuran-3(S)- Oxy)-quinazolin-6-yl]amide, di-2(Z)-butenedioate. The CAS number is 850140-73-7; the m...
