4-Bromo-5-(difluoromethyl)-2-iodopyridine-3-sulfonyl chloride CAS 1807028-14-3

Description

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.

4-Bromo-5-(difluoromethyl)-2-iodopyridine-3-sulfonyl chloride (CAS 1807028-14-3) is a high-purity analytical reference standard with the molecular formula C6H2BrClF2INO2S and a molecular weight of 432.41 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine/iodine substitution, an aromatic ring system, 4-Bromo-5-(difluoromethyl)-2-iodopyridine-3-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
