【摘要】:目的:采用LC-MS對(duì)酒石酸唑吡坦片中的雜質(zhì)進(jìn)行結(jié)構(gòu)鑒定。方法:通過(guò)酸、堿、高溫、氧化和光照對(duì)酒石酸唑吡坦片中的雜質(zhì)進(jìn)行富集,采用液相色譜-超高分辨飛行時(shí)間質(zhì)譜對(duì)未知雜質(zhì)進(jìn)行鑒定,色譜柱為C_(18)(2.1 mm×100 mm,1.9μm),流動(dòng)相為10 mmol·L~(-1)乙酸銨溶液-甲醇-乙腈(53∶23∶18),采用ESI正離子模式進(jìn)行質(zhì)譜掃描。結(jié)果:結(jié)合酒石酸唑吡坦的處方工藝初步推測(cè)了6個(gè)雜質(zhì)的化學(xué)結(jié)構(gòu)。雜質(zhì)1:4-(二甲胺基)-3-(6-甲基-2-對(duì)甲苯基咪唑并[1,2-a]吡啶-3-基)-4-氧代丁酸;雜質(zhì)4:N-甲基-2-(6-甲基-2-對(duì)甲苯基咪唑并[1,2-a]吡啶-3-基)乙酰胺;雜質(zhì)5:2-羥基-N,N-二甲基-2-(6-甲基-2-對(duì)甲苯基咪唑并[1,2-a]吡啶-3-基)乙酰胺;雜質(zhì)6:N,N-二甲基-2-(6-甲基-2-對(duì)甲苯基咪唑并[1,2-a]吡啶-3-基)-2-氧代乙酰胺;雜質(zhì)7:N,N-二甲基-2-(6-甲基-2-對(duì)甲苯基-2,3-二氫咪唑并[1,2-a]吡啶-3-基)乙酰胺;雜質(zhì)8:6-甲基-2-對(duì)甲苯基咪唑并[1,2-a]吡啶-3-甲醛。它們都具有6-甲基-2-苯基咪唑并[1,2-a]吡啶的母核。結(jié)論:超高分辨飛行時(shí)間質(zhì)譜技術(shù)能夠有效地用于藥物中雜質(zhì)的鑒定,酒石酸唑吡坦雜質(zhì)研究可為其質(zhì)量控制和工藝優(yōu)化提供參考依據(jù)。
[Abstract]:Objective: to identify the impurities in zolpidem tartrate tablets by LC-MS. Methods: the impurities in zolpidem tartrate tablets were enriched by acid, alkali, high temperature, oxidation and illumination. Unknown impurities were identified by liquid chromatography-ultrahigh resolution time-of-flight mass spectrometry. The chromatographic column was Che _ (18) ~ (18) mm 脳 10 ~ (10) mmol 路L ~ (-1) mmol 路L ~ (-1) 路L ~ (-1) acetonitrile-methanol-acetonitrile 53: 23: 18. The mass spectrometry was performed by ESI positive ion mode. Results: the chemical structures of the six impurity were preliminarily inferred by combining the prescription of zolpidem tartrate with 10 mmol 路L ~ (-1) acetonitrile solution. The impurity is 1: 4-dimethylamino-6-methyl-2-methyl-2-methyl-imidazolido [1za2-a] pyridine -3-methyl-4-oxobutyric acid; Impurity 4: N- methyl-2-methyl-2-methyl-2-methyl-2-methyl-4-methyl-imidazolidazolido [1 (2-a) pyridine-3-yl) acetamide; impurity 5: 2-hydroxy-N-dimethyl-2-methyl-2-methyl-2-methyl-2-methyl-2-methyl-2-methyl-2-methyl-2-methyl-2-methyl-2-methyl-4-methyl-imidazolyl [1 (2-a] pyridyl-3-yl) acetamide; Impurity 6: N- N- dimethyl-2-oxoacetamide; impurity 7: N- N- dimethyl-2-oxoacetamide; impurity 7: N-, N-dimethyl-2-oxoacetamide; impurity 7: N-, N-dimethyl-2-oxoacetamide; impurity 7: N-, N-dimethyl-2-oxoacetamide; impurity 7: N-, N-dimethyl-2-oxo-6-methyl-2-dihydroimidazolium and [12-a] pyridine-3-yl) acetamide; Impurity 8: 6- methyl-2- p-methylimidazo [1h2a] pyridine-3-formaldehyde. They all have the parent nucleus of 6-methyl-2-phenyimidazo [1h2a] pyridine. Conclusion: ultrahigh resolution time-of-flight mass spectrometry can be used to identify impurities in drugs. The study on the impurity of zolpidem tartrate can provide reference for its quality control and process optimization.
