Method Validation and Quality Control Once an impurity is identified and a regulatory limit is established, the analytical method used to measure it must be validated. Unlike simple contaminants, these species possess specific identities and toxicological profiles that demand rigorous characterization.

These regulations mandate that developers identify potential impurities early in the development process and establish strict acceptance criteria. A thorough risk assessment, often utilizing the ICH M7 guideline on mutagenic impurities, determines the level of control required.
Validation parameters include specificity, linearity, accuracy, precision, and detection/quantitation limits. These methods reveal the molecular weight and structural fragments of the unknown entity, allowing chemists to pinpoint the exact chemical transformation that occurred during synthesis.
