The pharmaceutical industry is a significant contributor to environmental pollution and economic inefficiencies due to high waste generation, energy consumption, and toxic by-products. This study aims to evaluate the effectiveness of green chemistry approaches in pharmaceutical synthesis to reduce environmental impact, improve reaction efficiency, and enhance cost-effectiveness. The objectives of this research were to compare green chemistry synthesis methods with traditional synthesis protocols in terms of reaction yield, product purity, environmental impact (waste generation, energy consumption, and CO₂ emissions), and economic feasibility.

In this study, we synthesized three model compounds (Compound A, Compound B, and Compound C) using both conventional and green synthesis methods. We employed green synthesis techniques that incorporated renewable feedstocks, catalytic processes, and waste minimization strategies. Data analysis included statistical evaluations such as t-tests and ANOVA to determine the significance of differences in yields, purity, and environmental metrics.

The results demonstrated that green synthesis methods significantly improved reaction yields and product purity by more than 10% compared to conventional methods. Environmental assessments showed a remarkable reduction in waste generation by approximately 65%, energy consumption by 60%, and CO₂ emissions by over 60%. Additionally, our cost analysis revealed a 25% reduction in overall synthesis costs with green chemistry protocols, driven by lower material and labor expenses. These findings align with previous studies highlighting the benefits of atom economy, waste reduction, and energy efficiency in green synthesis practices.
