Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(bromomethyl)-4-fluoro-pyridine-2-carbonitrile.
CATO supplies 5-(bromomethyl)-4-fluoro-pyridine-2-carbonitrile (CAS 2855247-71-9), a certified reference material (molecular formula C7H4BrFN2, MW 215.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H4BrFN2, 5-(bromomethyl)-4-fluoro-pyridine-2-carbonitrile contains a nitrile group, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
