Veterinary API Reference Standards
Veterinary API reference standards — antiparasitic, antibacterial and NSAID actives
CAS-indexed reference standards for veterinary-sector active pharmaceutical ingredients, released lot by lot for assay calibration, related-substance profiling and residue-method development.
How veterinary API reference standards are characterised and released
Veterinary-sector actives are analysed under the same chromatographic discipline as any other API: a characterised standard of known identity and assigned purity is what turns a retention time into a quantitative result. This hub lists the macrocyclic lactone, benzimidazole, fluoroquinolone, amphenicol, macrolide and NSAID actives most often requested by contract analytical laboratories and formulation development groups.
Every material is released against a documented HPLC purity specification with identity confirmed by 1H-NMR and LC-MS. Typical applications are content assay calibration, related-substance and isomer-ratio determination, residue-method development in feed and biological matrices, and system suitability for compendial-style chromatography.
These materials are supplied strictly as analytical reference standards for in-vitro laboratory research and analytical testing. They are not supplied for administration to humans or animals, and no therapeutic, dosing or veterinary-practice guidance is provided with them.

Frequently asked
- Are these standards suitable for residue analysis in feed or biological matrices?
- Yes. Each lot reports an assigned chromatographic purity so it can be used as the calibrant in a residue method, and deuterated internal standards for isotope-dilution quantitation are listed in the stable isotope hub.
- Can veterinary API standards be supplied in gram or kilogram quantities?
- Milligram pack sizes are priced openly on each product page. Volumes from 100 g to 1 kg and above are quoted individually through the bulk enquiry track after buyer verification.
- Do you supply licence-restricted veterinary actives?
- Materials that require an import or handling licence in the destination country are listed without public pricing and released only after documentation review. Submit the enquiry form with your institution details and permit reference to open a verification file.
