Chemical Structure

2-Fluoro-4-iodobenzene-1-sulfonamide CAS 874814-67-2 chemical structure

Description

The occurrence of 2-Fluoro-4-iodobenzene-1-sulfonamide 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.

2-Fluoro-4-iodobenzene-1-sulfonamide (CAS 874814-67-2) is a high-purity analytical reference standard with the molecular formula C6H5FINO2S and a molecular weight of 301.08 g/mol.

Structurally, 2-Fluoro-4-iodobenzene-1-sulfonamide (C6H5FINO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 301.08 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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-Fluoro-4-iodobenzene-1-sulfonamide 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.
