How is analytical R&D different from routine quality control?

Analytical R&D focuses on developing and improving analytical methods for new drugs, formulations, impurities, and stability studies. It helps determine the best way to test a pharmaceutical product during development. Routine Quality Control (QC), on the other hand, uses approved and validated methods to test finished products and raw materials against set quality standards before release. In simple terms, analytical R&D develops and validates the testing methods, while routine QC uses those methods to check product quality consistently. Both are important for maintaining safe, effective, and reliable pharmaceutical products.
