Simultaneous Determination of Two Potential Genotoxic Impurities in Zolmitriptan Using Liquid Chromatography- Tandem Mass Spectrometry
The detection and quantification of potential genotoxic impurities (PGIs) play an important role in the pharmaceutical industry. The industry needs highly selective and sensitive analytical methods for trace level quantification of these PGIs in drug substances. A sensitive and stability indicating LC-MS/MS method was developed for the simultaneous detection and quantification of (S)-4-(4-amino...
متن کاملGenotoxic Impurities in Pharmaceuticals
Genotoxic compounds induce genetic mutations and/or chromosomal rearrangements and can therefore act as carcinogenic compounds (McGovern and Jacobson-Kram, 2006). These compounds cause damage to DNA by different mechanisms such as alkylation or other interactions that can lead to mutation of the genetic codes. In general, chemists employ the terms "genotoxic" and "mutagenic" synonymously; howev...
متن کاملA selective and sensitive LC-MS/MS method for the simultaneous determination of two potential genotoxic impurities in celecoxib
Background: Impurity profiling is now receiving critical attention from regulatory authorities. For trace level quantification of potential genotoxic impurities (PGIs), conventional analytical techniques like high-performance liquid chromatography (HPLC) and gas chromatography (GC) are inadequate; consequently, there is a great need to apply hyphenated analytical techniques to develop sensitive...
