Chemical Structure
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-(4-Bromo-1-ethyl-3-methyl-1H-pyrazol-5-yl)-N,N-dimethylmethanamine (CAS 1355214-62-8) is a high-purity analytical reference standard with the molecular formula C9H16BrN3 and a molecular weight of 246.15 g/mol.
The molecular framework of 1-(4-Bromo-1-ethyl-3-methyl-1H-pyrazol-5-yl)-N,N-dimethylmethanamine (C9H16BrN3) is characterized by a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-(4-Bromo-1-ethyl-3-methyl-1H-pyrazol-5-yl)-N,N-dimethylmethanamine 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.
