Description

6-Bromonicotinic acid 6-bromo-3-pyridine carboxylic acid 6-Bromopyridine-3-carboxylic acid 2-Bromo-5-pyridinecarboxylic acid 6-Bromo-3-pyridinecarboxylic acid 2-Bromopyridine-5-carboxylic acid 6311-35-9 (CAS 6311-35-9) is a high-purity analytical reference standard with the molecular formula C6H10BrNO2 and a molecular weight of 208.05 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 6-Bromonicotinic acid 6-bromo-3-pyridine carboxylic acid 6-Bromopyridine-3-carboxylic acid 2-Bromo-5-pyridinecarboxylic acid 6-Bromo-3-pyridinecarboxylic acid 2-Bromopyridine-5-carboxylic acid 6311-35-9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
