Chemical Structure
Description
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.
4-bromanyl-2-chloranyl-5-fluoranyl-pyridine 4-bromo-2-chloro-5-fluoropyridine 884495-10-7 A842606 (CAS 884495-10-7), molecular formula C5H2BrClFN and molecular weight 210.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-bromanyl-2-chloranyl-5-fluoranyl-pyridine 4-bromo-2-chloro-5-fluoropyridine 884495-10-7 A842606 (C5H2BrClFN) is characterized by a nitrile group, fluorine/chlorine/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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
