Chemical Structure
Description
2-(4-(Bromomethyl)phenyl)pyridine hydrochloride (CAS 257907-04-3) is a high-purity analytical reference standard with the molecular formula C12H10BrNHCl and a molecular weight of 284.58 g/mol.
The molecular framework of 2-(4-(Bromomethyl)phenyl)pyridine hydrochloride (C12H10BrNHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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-(4-(Bromomethyl)phenyl)pyridine hydrochloride 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.
