The present work describes the synthesis and characterization of four potential impurities of Vigabatrin (1) namely 2-(2-aminobut-3-enyl)malonic acid (2) (Vigabatrin USP impurity-E), 2-(2-oxo-5-vinylpyrrolidin-1-yl)acetic acid (3) (USP Tablets impurity), 4-aminohexanoic acid (4) and 2,2′-oxo-5,5′-bispyrrolidinyl ether (5). Compound 4 is a possible process related impurity of 1 where as compound 5 is a
摘要 本工作描述了 Vigabatrin (1) 的四种潜在杂质的合成和表征,即 2-(2-aminobut-3-enyl)丙二酸 (2)(Vigabatrin USP 杂质-E)、2-(2-oxo- 5-乙烯基吡咯烷-1-基)乙酸(3)(USP片剂杂质)、4-氨基己酸(4)和2,2'-氧代-5,5'-双吡咯烷基醚(5)。化合物4是1的可能的工艺相关杂质,其中化合物5是5-乙氧基-2-吡咯啉酮(16)的工艺相关杂质。所有这些杂质都会对药品的质量产生重大影响。这项工作对仿制药行业非常有用。图形概要
