Abstract: Analytical method development and validation forms the foundation of modern pharmaceutical analysis and ensures that new drug molecules are characterized with accuracy, precision, and reproducibility. The increasing complexity of molecular structures, regulatory frameworks, and therapeutic demands has placed a premium on robust analytical techniques that support quality assurance and patient safety. This paper explores the significance of developing reliable analytical methods, highlights validation parameters as per International Council for Harmonisation (ICH) guidelines, and examines the role of chromatographic, spectroscopic, and hyphenated techniques in ensuring regulatory compliance. Furthermore, emerging trends such as Quality by Design (QbD), Process Analytical Technology (PAT), and artificial intelligence-driven predictive modeling are discussed to show how the analytical landscape is evolving. Practical case studies and tabular summaries are provided to illustrate key aspects of pharmaceutical method development and validation.
Keywords: Analytical method development, Validation, Novel drug molecules, Quality assurance, Regulatory compliance
