Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.49 g/mol gives 2-Bromo-5-fluorophenylhydrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Bromo-5-fluorophenylhydrazine (CAS 776239-07-7), a certified reference material (molecular formula C6H6BrFN2HCl, MW 241.49 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-5-fluorophenylhydrazine (C6H6BrFN2HCl) is characterized by a nitrile group, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-5-fluorophenylhydrazine 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.
