Analytical method validation is required when a new analytical method is developed or when an existing method is changed significantly. In the pharmaceutical industry, validation confirms that a method is suitable for its intended purpose and can provide accurate, reliable, and consistent results. It is commonly required for assay testing, impurity testing, stability studies, release testing, and regulatory submissions. As part of analytical research and development in pharmaceutical industry, method validation may also be required when an analytical method is transferred to another laboratory, when there are major changes in the product or manufacturing process, or when the testing procedure is modified. Depending on the method and its purpose, characteristics such as accuracy, precision, specificity, linearity, range, sensitivity, and robustness may be evaluated. A reliable analytical R&D pharma process helps ensure that analytical methods meet their intended requirements and generate dependable results. An experienced pharma analytical R&D company can support method development, validation, documentation, and related analytical studies needed for pharmaceutical product development and regulatory requirements.
