: Pharmaceutical organic chemistry is an important part of Pharmaceutical Research and Development unit, since it involves preparation of novel or modification of already existing molecules to extract the therapeutic application of these molecules. This book deals with different types of experiments, where the major emphasis is given on various basic techniques of Organic chemistry like melting point, boiling point, crystallization, distillation, and calibration of thermometer. It also includes identification of organic compound of various functional groups from carboxylic acid, Phenols, ketons, aldehyde….etc, with specific reaction procedure and its chemical reaction. It also covers experimental methods consisting of the derivatives preparations of functional groups. The book also covers some Organic preparation /Synthesis of compounds with reaction, principle and mechanism These experiments are selected in such a manner that the reader should get a in depth knowledge about the medicinal chemistry practicals. All comments and suggestions will be received with gratitude. I am very much grateful to KLE Academy of Higher Education and Research, all my beloved teachers, parents, wife for their constant support and encouragement.
