Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 277.59 g/mol gives 5-Bromo-2-piperidinopyridine, HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-piperidinopyridine, HCl (CAS 1242336-67-9), molecular formula C10H13BrN2HCl and molecular weight 277.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromo-2-piperidinopyridine, HCl (C10H13BrN2HCl) 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), 5-Bromo-2-piperidinopyridine, HCl 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.
