Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-CHLORINE-5-BROMINE PYRIDINE 2-CHLORO-5-BROMOPYRIDINE 5-BROMO-2-CHLOROPYRIDINE 53939-30-3 BC002093 PYRIDINE, 5-BROMO-2-CHLORO-.
CATO supplies 2-CHLORINE-5-BROMINE PYRIDINE 2-CHLORO-5-BROMOPYRIDINE 5-BROMO-2-CHLOROPYRIDINE 53939-30-3 BC002093 PYRIDINE, 5-BROMO-2-CHLORO- (CAS 53939-30-3), a certified reference material (molecular formula C5H9BrClN, MW 198.49 g/mol) for analytical method development and quality control.
Structurally, 2-CHLORINE-5-BROMINE PYRIDINE 2-CHLORO-5-BROMOPYRIDINE 5-BROMO-2-CHLOROPYRIDINE 53939-30-3 BC002093 PYRIDINE, 5-BROMO-2-CHLORO- (C5H9BrClN) contains chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 198.49 g/mol, it falls into the medium-molecular-weight range. 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.
