Certified Impurity Standards

Certified Impurity Standards are high-purity reference materials representing known process, degradation, or genotoxic impurities associated with active pharmaceutical ingredients and specialty chemicals. They are used for method development, validation, system suitability, and routine QC testing on analytical platforms such as HPLC, UHPLC, GC, LC-MS, and NMR. Each standard is supplied with defined identity, purity, and characterization data to support reliable quantification at trace levels and compliance with regulatory monographs. Typical users include pharmaceutical manufacturers, generic drug developers, CDMOs, contract testing laboratories, and academic research groups working under GMP or ICH-aligned quality frameworks.
