1,3-Bis(4-bromophenyl)-1H-pyrazole-4-carbaldehyde CAS 618098-54-7

Description

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.

1,3-Bis(4-bromophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618098-54-7), molecular formula C16H10Br2N2O and molecular weight 406.07 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H10Br2N2O, 1,3-Bis(4-bromophenyl)-1H-pyrazole-4-carbaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 406.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 1,3-Bis(4-bromophenyl)-1H-pyrazole-4-carbaldehyde 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.
