Organic and mutagenic impurities

We are Azierta, experts in organic and mutagenic impurities.

When an impurity in a medication reaches or exceeds the qualification level, the manufacturer must justify the toxicity of the impurity in accordance to the established regulations for organic impurities ICH Q3A/Q3B and mutagenic impurities ICH M7.
To justify organic and mutagenic impurities, it is necessary to identify the impurity and analyze it in order to subsequently assess the risk it may involve for human health.

At Azierta, we offer a comprehensive service covering everything from the structural elucidation of impurities to toxicological evaluation and characterisation. To do this, we use a specialised process:
