Reference standard categories
Each category page sets out how the materials are characterised, what the Certificate of Analysis covers, and which standards are currently released.
Analytical Reference Standards
Lot-released analytical reference standards characterised by 1H-NMR, LC-MS, HPLC-UV and Karl Fischer titration, supplied strictly for in-vitro laboratory research and analytical testing.
14 released standards
Impurity Standards
Characterised impurity standards for related-substance chromatographic methods, limit testing and analytical method validation under ICH Q3A and Q3B control strategies.
3 released standards
Stable Isotope Standards
Deuterium and carbon-13 labelled internal standards for isotope-dilution LC-MS/MS quantitation, recovery assessment and bioanalytical method validation.
3 released standards
Veterinary API Reference Standards
CAS-indexed reference standards for veterinary-sector active pharmaceutical ingredients, released lot by lot for assay calibration, related-substance profiling and residue-method development.
10 released standards
Peptide Reference Standards
Lyophilised peptide reference standards released lot by lot with identity confirmed by LC-MS peptide mapping and chromatographic purity determined by HPLC-UV, supplied strictly for in-vitro laboratory research and analytical testing.
