Description
As a certified reference material (CRM), 857641-46-4 2-(4-Bromo-1H-pyrazol-1-yl)pyrimidine DTXSID00671956 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.
857641-46-4 2-(4-Bromo-1H-pyrazol-1-yl)pyrimidine DTXSID00671956 (CAS 857641-46-4) is a high-purity analytical reference standard with the molecular formula C7H5BrN4 and a molecular weight of 225.05 g/mol.
The molecular framework of 857641-46-4 2-(4-Bromo-1H-pyrazol-1-yl)pyrimidine DTXSID00671956 (C7H5BrN4) is characterized by a nitrile group, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
