Metabolism Studies

Charles River has over 30 years of experience performing metabolism studies to support the development of veterinary, biocide and agrochemical compounds. Working with all common livestock species and all routes of administration, we routinely conduct studies to meet all major global regulatory requirements.

  • Dose formulation, ranging from aquatic-based solutions to oil-based suspensions
  • Comprehensive, integrated profiling and identification of metabolites in excreta, milk, eggs and tissues
  • Chromatographic and isolation technologies (supported by Q-ToF and IT-ToF mass spectrometry)
  • Access to NMR for definitive metabolite identification
  • Metabolite reference standards for future structural confirmation provided by synthetic chemistry group
