Impurity levels need to be understood and controlled for the benefit of safely administering pharmaceutical products to humans. Impurities impact not only the safety of drugs, but also the development time if not addressed early during the scale up process. Learn about elemental impurities and the new ICH Q3D and USP <232> and <233> guidelines here.

Regis offers services for impurity isolation, impurity characterization (including genotoxic impurity identification), synthesis scale-up for reference standards, and qualification for cGMP reference standards.

The purpose of stability testing is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light. Stability studies test those attributes of the drug substance that are susceptible to change during storage and are likely to influence quality, safety, and efficacy. The testing includes as appropriate, the physical and chemical attributes.
