Compared with other compounds in its class, the molecular weight of 345.86 g/mol gives 2,6-Bis(bromomethyl)pyridine Hydrobromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Bis(bromomethyl)pyridine Hydrobromide (CAS 73004-40-7), molecular formula C7H7Br2NHBr and molecular weight 345.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Bis(bromomethyl)pyridine Hydrobromide (C7H7Br2NHBr) 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.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
