Chemical Structure
Description
As a certified reference material (CRM), n-(3-Bromo-4-fluorobenzyl)-2-(1h-pyrazol-1-yl)ethan-1-amine 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.
n-(3-Bromo-4-fluorobenzyl)-2-(1h-pyrazol-1-yl)ethan-1-amine (CAS 1293072-18-0), molecular formula C12H13BrFN3 and molecular weight 298.15 g/mol, is a CATO reference standard with documented purity and traceability.
n-(3-Bromo-4-fluorobenzyl)-2-(1h-pyrazol-1-yl)ethan-1-amine (C12H13BrFN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
