The detection and characterization of impurities in pharmaceuticals are pivotal aspects of ensuring the safety, efficacy, and quality of drug products. This review provides a comprehensive overview of the analytical techniques employed in the identification and quantification of impurities at various stages of pharmaceutical development, manufacturing, and quality control. Chromatographic methods, including High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC), are foundational for their ability to separate complex mixtures. Mass spectrometry (MS) and Nuclear Magnetic Resonance (NMR) spectroscopy offer high sensitivity and structural insights crucial for impurity characterization. The integration of these techniques, such as in Liquid Chromatography-Mass Spectrometry (LC-MS) and Liquid Chromatography-Nuclear Magnetic Resonance (LC-NMR), provides a synergistic approach to impurity analysis. Advanced hyphenated techniques enhance specificity and accuracy, allowing for real-time monitoring and dynamic adjustments during analysis. Challenges in chiral separation, degradation product analysis, and method validation are addressed through the sophistication of these methodologies. The review underscores the significance of data analysis and validation processes, ensuring the reliability of results in compliance with stringent regulatory standards. Overall, the continuous evolution and integration of analytical techniques play a pivotal role in shaping the future of pharmaceutical research, development, and quality assurance, emphasizing the commitment to producing pharmaceuticals of the highest quality and safety standards.
