2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-5-fluorobenzamide CAS 1154950-19-2

Description

As a certified reference material (CRM), 2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-5-fluorobenzamide 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.

2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-5-fluorobenzamide (CAS 1154950-19-2), molecular formula C12H11BrFN3O and molecular weight 312.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-5-fluorobenzamide (C12H11BrFN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
