Advancing Pharmaceutical Chemistry Through Green Analytical Methods: A Comprehensive Review

Abstract

The increasing demand for sustainable practices in pharmaceutical chemistry has led to the development of Green Analytical Chemistry (GAC), which minimizes environmental impact while ensuring analytical precision. This review explores key advancements in green chromatographic and spectroscopic techniques, emphasizing the reduction of hazardous solvents, the use of eco-friendly reagents, and energy-efficient analytical methods. Miniaturization and automation have further enhanced efficiency by reducing sample volume, reagent consumption, and waste generation. The regulatory landscape is also evolving, with international agencies such as the ICH, EPA, and EMA promoting greener analytical methodologies. Despite challenges like high initial costs and validation complexities, the future of green pharmaceutical analysis is promising, driven by AI integration, solvent-free techniques, and real-time monitoring technologies. The adoption of sustainable analytical practices will not only improve environmental safety but also enhance operational efficiency in the pharmaceutical industry.
