2-(Difluoromethyl)-4-hydroxy-6-iodopyridine-3-carbonyl chloride CAS 1805995-29-2

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.

CATO supplies 2-(Difluoromethyl)-4-hydroxy-6-iodopyridine-3-carbonyl chloride (CAS 1805995-29-2), a certified reference material (molecular formula C7H3ClF2INO2, MW 333.46 g/mol) for analytical method development and quality control.

2-(Difluoromethyl)-4-hydroxy-6-iodopyridine-3-carbonyl chloride (C7H3ClF2INO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system. 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.
