5-Bromo-2-carboxy-3-fluoropyridine 5-Bromo-3-fluoropicolinic acid 5-bromo-3-fluoropyridine-2-carboxylic acid 669066-91-5 CAS 669066-91-5

Description

5-Bromo-2-carboxy-3-fluoropyridine 5-Bromo-3-fluoropicolinic acid 5-bromo-3-fluoropyridine-2-carboxylic acid 669066-91-5 (CAS 669066-91-5) is a high-purity analytical reference standard with the molecular formula C6H9BrFNO2 and a molecular weight of 226.04 g/mol.

The molecular framework of 5-Bromo-2-carboxy-3-fluoropyridine 5-Bromo-3-fluoropicolinic acid 5-bromo-3-fluoropyridine-2-carboxylic acid 669066-91-5 (C6H9BrFNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
