Pharmaceutical, Veterinary & Medical Research Reference StandardsPharmaceutical, Veterinary & Medical Research Reference Standards

We offer a comprehensive range of pharmaceutical, veterinary and medical research reference standards including metabolites and impurities, and their stable isotope labelled analogues. We make every effort to provide a complete set of reference standards for your research, analysis and screening needs. Many of these reference standards are not available from any other source. Our range includes:

  • Active pharmaceutical ingredients
  • Metabolites including conjugates such as glucuronides
  • Degradation products and process impurities
  • Genotoxic impurities
  • Related substances for pharmacopeial updates
  • Stable isotope-labelled analogues

All reference standards are fully characterised with supporting analytical data and accompanying certification document.
