Spectroscopic techniques play a vital role in this process by providing rapid, reliable, and non-destructive analysis of drug substances and formulations. Among these, Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR), and Raman spectroscopy are widely employed due to their complementary analytical capabilities. FTIR is primarily used for functional group identification and compatibility studies, while NMR offers detailed structural elucidation and impurity profiling at the molecular level. Raman spectroscopy, with its minimal interference from water and suitability for in situ analysis, is particularly useful for polymorphic characterisation and real-time monitoring. These techniques collectively support critical applications such as structural confirmation, detection of degradation products, polymorphism analysis, and drug–excipient interaction studies. Their combined use enhances analytical accuracy and provides comprehensive insight into pharmaceutical systems. With ongoing advancements in instrumentation, chemometrics, and process analytical technology, spectroscopic methods are expected to play an increasingly significant role in modern pharmaceutical analysis and quality control.</p> Kiran Kumar Byram Chirag Patel Sagar Patel Shravan Kumar Muthyam Copyright (c) 2026 https://creativecommons.org/licenses/by-nc/4.0 2026-05-06 2026-05-06 1 7 10.37022/jpmhs.v9i2.192
