HPLC and UV Spectroscopy in Pharmaceutical Analysis

Abstract

Ultraviolet (UV) spectroscopy and High-Performance Liquid Chromatography (HPLC) are two essential analytical methods that are frequently employed in pharmaceutical analysis for regulatory compliance, quality assurance, and medication development. Pharmaceutical substances, such as active pharmaceutical ingredients (APIs), contaminants, and degradation products, can be separated, identified, and quantified using high-performance liquid chromatography (HPLC), a very sensitive and accurate chromatographic technology. It is essential for pharmacokinetic research, stability testing, and bioequivalence evaluations. However, UV spectroscopy is a quick and inexpensive analytical method that helps with both qualitative and quantitative characterization of drug compounds by measuring how much ultraviolet light they absorb. It is widely used for pharmaceutical ingredient concentration determination, dissolving research, and purity testing. For frequent quality checks, UV spectroscopy offers a more straightforward and non-destructive method, even if HPLC gives better selectivity and resolution. Pharmaceutical analysis is more accurate and efficient when these two methods are combined. A popular technique for tracking drug formulations, identifying fake drugs, and guaranteeing batch-to-batch uniformity in production is HPLC combined with UV detection, or HPLC-UV. The concepts, procedures, and comparative uses of HPLC and UV spectroscopy in pharmaceutical analysis are examined in this paper. Their benefits, drawbacks, and most current developments in analytical technology are also covered. Researchers and pharmaceutical experts must be aware of these methods in order to guarantee the safety, effectiveness, and adherence to international regulatory requirements of drugs
