4-fluoro-2-iodobenzene-1-sulfonyl chloride CAS 874814-68-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-fluoro-2-iodobenzene-1-sulfonyl chloride.

CATO supplies 4-fluoro-2-iodobenzene-1-sulfonyl chloride (CAS 874814-68-3), a certified reference material (molecular formula C6H3ClFIO2S, MW 320.51 g/mol) for analytical method development and quality control.

The molecular framework of 4-fluoro-2-iodobenzene-1-sulfonyl chloride (C6H3ClFIO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
