Description
Fenbendazole Veterinary API Reference Standard is supplied as a characterised, lot-controlled analytical material for in-vitro laboratory research and analytical testing. Each lot is released against a documented HPLC purity specification of ≥ 99.3% with a Certificate of Analysis referencing the tested lot number.
Reference calibrant for benzimidazole assay methods, oxfendazole/oxibendazole cross-specificity checks and residue-method development in analytical laboratories.
Identity is confirmed by 1H-NMR and LC-MS, chromatographic purity by HPLC-UV, water content by Karl Fischer titration and residual solvents by headspace GC. The material is packed in a sealed amber vial under argon with desiccant and is not supplied for administration to humans or animals.
Supplied for in-vitro laboratory research and analytical testing only. Not for human or veterinary use, consumption, or diagnostic purposes.
