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.

6-Bromopyridine-2-carboxylic acid 6-bromopicolinic acid 6-bromo-2-pyridinecarboxylic acid 6-bromo-2-pyridine carboxylic acid 2-bromopyridine-6-carboxylic acid 6-bromopyridine-2-formic acid 5-bromo-2-pyridine carboxylic acid 2-bromo pyridine-6-carboxylic acid 21190-87-4 (CAS 21190-87-4), molecular formula C6H10BrNO2 and molecular weight 208.05 g/mol, is a CATO reference standard with documented purity and traceability.

6-Bromopyridine-2-carboxylic acid 6-bromopicolinic acid 6-bromo-2-pyridinecarboxylic acid 6-bromo-2-pyridine carboxylic acid 2-bromopyridine-6-carboxylic acid 6-bromopyridine-2-formic acid 5-bromo-2-pyridine carboxylic acid 2-bromo pyridine-6-carboxylic acid 21190-87-4 (C6H10BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
