Description

Compared with other compounds in its class, the molecular weight of 321.50 g/mol gives 6-Fluoro-4-iodopyridine-2-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Fluoro-4-iodopyridine-2-sulfonyl chloride (CAS 1393538-76-5), molecular formula C5H2ClFINO2S and molecular weight 321.50 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Fluoro-4-iodopyridine-2-sulfonyl chloride (C5H2ClFINO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 6-Fluoro-4-iodopyridine-2-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.
