Compared with other compounds in its class, the molecular weight of 217.06 g/mol gives 2-Bromo-1-(3-methyl-1H-pyrazol-1-yl)propan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-1-(3-methyl-1H-pyrazol-1-yl)propan-1-one (CAS 69413-07-6), molecular formula C7H9BrN2O and molecular weight 217.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-1-(3-methyl-1H-pyrazol-1-yl)propan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2-Bromo-1-(3-methyl-1H-pyrazol-1-yl)propan-1-one 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.
