Chemical Structure

7-Iodobenzofuran-5-sulfonylchloride CAS 856678-58-5 chemical structure

Description

The occurrence of 7-Iodobenzofuran-5-sulfonylchloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Iodobenzofuran-5-sulfonylchloride (CAS 856678-58-5), molecular formula C8H4ClIO3S and molecular weight 342.54 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H4ClIO3S, 7-Iodobenzofuran-5-sulfonylchloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 7-Iodobenzofuran-5-sulfonylchloride 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.
