Abstract

The invention relates to the technical field of analytical chemistry and discloses a method for detecting afatinib dimaleate isomer and main degradation impurities through a high performance liquid chromatography.According to the method, afatinib dimaleate raw materials or preparations are compounded into a detection solution with diluent, bonding amylose-trichlorobenzene carbamic acid ester serves as a stationary phase, a normal hexane-ethanol-organic base solution serves as a mobile phase for isocratic elution, and an HPLC spectrogram is recorded under afatinib absorption wavelength.According to the method, a chromatographic column with trichlorobenzene carbamic acid ester serving as a filling material, the normal hexane-ethanol-organic base solution serves as the mobile phase, the content of isomers existing in afatinib dimaleate and preparations thereof can be measured quantitatively, afatinib, the isomers and the main impurities can be separated completely, the peak pattern is good, the method meets the specifications in Chinese Pharmacopoeia, quality of afatinib dimaleate and afatinib dimaleate preparation products is effectively controlled, and the method is great 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 maleic acid afatinib isomers and mainly degrading impurities 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...
