Residual Solvents

Meaning

Residual solvents are volatile organic chemicals that are used or produced in the manufacturing process of drug substances, excipients, or dietary supplements but are not completely removed by the final processing steps. These trace impurities are subject to strict regulatory limits because their presence, even at low levels, can pose potential toxicity risks to human health. Their quantification is a crucial aspect of quality control in the pharmaceutical and supplement industries.
