Impurities in drug substances or pharmaceutical products are any chemical substances that are not the Active Pharmaceutical Ingredient (API) or an excipient, and they can impact drug safety and efficacy. Their identification, quantification, and control are critical throughout the drug development process, as they may arise from materials, by-products, degradation, or packaging.

We also offer advanced methods for detecting NDSRIs (Nitrosamines Derived from Ingredient-Related Substances), a growing concern in pharmaceutical safety, ensuring your products meet the highest standards.
