Chemical Structure

3-Fluoro-2-iodobenzenesulfonamide CAS 1261744-64-2 chemical structure

Description

The occurrence of 3-Fluoro-2-iodobenzenesulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Fluoro-2-iodobenzenesulfonamide (CAS 1261744-64-2), molecular formula C6H5FINO2S and molecular weight 301.08 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system, 3-Fluoro-2-iodobenzenesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
