The Acanthus Research Inc. range of pharmaceutical, metabolite and impurity standards and their stable isotope labelled analogues is focused on products that are currently under development by the generic industry. We make every effort to provide a complete set of pharmaceutical standards and metabolites for bio-analytical studies. Many of these molecules are not available from any other source.

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

All reference standards are fully characterised with supporting analytical data and accompanying certification document. Acanthus Research matches or exceeds the industry practices for certification. Furthermore, Acanthus Research offers customised certification to meet varied needs in the pharmaceutical industry.
