2-(4-Bromo-1H-pyrazol-1-yl)-1-(piperazin-1-yl)ethanone dihydrochloride CAS 1006348-89-5

Description

As a certified reference material (CRM), 2-(4-Bromo-1H-pyrazol-1-yl)-1-(piperazin-1-yl)ethanone dihydrochloride 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-(4-Bromo-1H-pyrazol-1-yl)-1-(piperazin-1-yl)ethanone dihydrochloride (CAS 1006348-89-5) is a high-purity analytical reference standard with the molecular formula C9H13BrN4OHCl and a molecular weight of 309.59 g/mol.

The molecular framework of 2-(4-Bromo-1H-pyrazol-1-yl)-1-(piperazin-1-yl)ethanone dihydrochloride (C9H13BrN4OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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.
