Chemical Structure
Description
The occurrence of 5-fluoro-1-benzofuran-2-sulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-fluoro-1-benzofuran-2-sulfonyl chloride (CAS 1592452-13-5) is a high-purity analytical reference standard with the molecular formula C8H4ClFO3S and a molecular weight of 234.63 g/mol.
The molecular framework of 5-fluoro-1-benzofuran-2-sulfonyl chloride (C8H4ClFO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
As a certified reference material (CRM), 5-fluoro-1-benzofuran-2-sulfonyl chloride 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.
