Residual Solvents

Residual solvents, formerly referred to as organic volatile impurities (OVIs), are trace level chemical residues that are used or produced in the manufacture of drug substances and excipients or in the preparation of drug products. They can also be byproducts formed during packaging and storage of the drug product.
