Experimental Medicinal Chemistry-I

This practical manual presents a comprehensive collection of experiments in pharmaceutical analysis, organic synthesis, and physical pharmacy. The analytical experiments introduce pharmacopoeial methods, standardization, titration, calculations, percentage purity, and quality control of drug substances. The organic synthesis section covers the preparation of medicinally important compounds and heterocyclic systems, emphasizing reaction principles, purification, theoretical yield, practical yield, and percentage yield. The physical pharmacy experiments demonstrate the determination of the partition coefficient of benzoic acid and salicylic acid and their relevance to drug absorption and membrane permeability. Each experiment is systematically organized with the aim, principle, reaction, requirements, procedure, observations, calculations, results, precautions, and pharmaceutical significance. The manual is designed to develop practical laboratory skills, analytical accuracy, scientific understanding, and safe laboratory practices while linking fundamental pharmaceutical chemistry concepts with applications in drug development, quality assurance, and research.
