Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.52 g/mol gives 4-Formyl-6-iodopyridine-2-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Formyl-6-iodopyridine-2-sulfonyl chloride (CAS 1393530-86-3), molecular formula C6H3ClINO3S and molecular weight 331.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Formyl-6-iodopyridine-2-sulfonyl chloride (C6H3ClINO3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
