Advancements in HPLC Techniques for Detecting and identification of Process-Related and Degradants Impurities in Pharmaceutical Compounds
Year: 2025
Type: article
Abstract: Advancements in High-Performance Liquid Chromatography (HPLC) have significantly improved the detection, identification and quantification of process-related impurities and degradants in pharmaceuticals. Key innovations include Ultra-High-Performance Liquid Chromatography (UHPLC), which provides enhanced resolution and sensitivity, and multi-dimensional chromatography for better separation of complex mixtures. The integration of HPLC with Mass Spectrometry, particularly LC-MS/MS and High-Resolution Mass Spectrometry (HRMS), enables precise identification and quantification of impurities at trace levels. Advanced detectors, such as Diode-Array Detection (DAD), fluorescence detection, and evaporative light scattering detection (ELSD), further enhance sensitivity and selectivity for various impurities. Chiral chromatography is employed to resolve enantiomeric impurities. Additionally, the use of greener solvents and inline HPLC for real-time monitoring contribute to more sustainable and efficient practices. These advancements collectively ensure the safety, purity, and regulatory compliance of pharmaceutical products.
