Chemical Structure

2-(Difluoromethyl)-5-iodo-3-methoxypyridine-6-sulfonyl chloride CAS 1806948-03-7 chemical structure

Description

The occurrence of 2-(Difluoromethyl)-5-iodo-3-methoxypyridine-6-sulfonyl chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Difluoromethyl)-5-iodo-3-methoxypyridine-6-sulfonyl chloride (CAS 1806948-03-7) is a high-purity analytical reference standard with the molecular formula C7H5ClF2INO3S and a molecular weight of 383.54 g/mol.

2-(Difluoromethyl)-5-iodo-3-methoxypyridine-6-sulfonyl chloride (C7H5ClF2INO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 2-(Difluoromethyl)-5-iodo-3-methoxypyridine-6-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
