Analytical methods including chromatographic methods are commonly used for the quantitative and qualitative analysis of raw materials, drug substances, drug products, and compounds in biological samples in pharmaceutical industry. The components monitored include chiral or achiral drugs, process impurities, residual solvents, excipients such as preservatives, degradation products, extractable and leachable from container and closure or manufacturing process, pesticide in drug product from plant origin, and metabolites.
Validation of an analytical method which is used during drug development and drug manufacturing is required to demonstrate that the methods are fit for their intended purpose. Additionally, the pharmaceutical industry around the world is subject to extensive regulations due to the nature of its products.
Analytical chemists play important roles in monitoring the drugs in their dosage forms and biological samples. From the viewpoints mentioned above, the title of this special issue was chosen so as to ask chemists to appreciate their great roles in chemistry science. This special issue features 8research articles. In this special issue, development of chromatographic methods such as high performance liquid chromatography, gas chromatography, micellar liquid chromatography, and their validations is presented.
The purpose of this special issue will be to serve as a guide to what chromatographic methods bring to analytical and medicinal chemistry and other pharmaceutical sciences as well as briefly review their role in drugs and the new developments and validation of assay methods of pharmaceutically active compounds. Also, recent developments of application, evaluation, and validation of chromatographic methods are focused on by key topics in drug developments and analysis by assessment of the distinguished authors of this special issue. We hope that the reader will find a number of topics of interest and that additional new ideas will emerge from this special issue.
