Organic volatile impurities (OVIs), generally represent the chemical compounds in products, and are mainly produced by incomplete removal of the residual solvent during the manufacturing of active pharmaceutical ingredients (APIs), excipients and drug products. Recognizing the fact that these OVIs have an obvious adverse effect on the quality, safety, stability, potency and other performance of the finish products or intermediates, complete or partial removal of a solvent or solvents is therefore a pivotal stage in many pharmaceutical processes. However, toxic solvents and correspondingly acceptable limits can vary in different pharmacopoeias. According to the ICH Q3C Guideline for Residual Solvents, the residual solvents can be defined into three classes based on their potential toxicity level:
Class Ⅰ: Residual solvents that are able to cause unacceptable toxicities such as human carcinogens, and environmental hazards
Class Ⅱ: Residual solvents with medium severe toxicities such as on-genotoxic animal carcinogens and certain causative agents that can lead to neurotoxicity or teratogenicity
Class Ⅲ: Residual solvents with the least toxic, are required with no health-based exposure limit
