Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Amino-1-(2-chloro-4-fluorobenzyl)pyrazole Hydrochloride (CAS 1147222-53-4), molecular formula C10H9ClFN3 and molecular weight 225.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H9ClFN3, 4-Amino-1-(2-chloro-4-fluorobenzyl)pyrazole Hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 4-Amino-1-(2-chloro-4-fluorobenzyl)pyrazole Hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
