Chemical Structure

2-Fluoro-5-nitrobenzenesulfonyl chloride CAS 713-21-3 chemical structure

Description

The occurrence of 2-Fluoro-5-nitrobenzenesulfonyl chloride is closely related to an amide group, 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.

CATO supplies 2-Fluoro-5-nitrobenzenesulfonyl chloride (CAS 713-21-3), a certified reference material (molecular formula C6H3ClFNO4S, MW 239.61 g/mol) for analytical method development and quality control.

The molecular framework of 2-Fluoro-5-nitrobenzenesulfonyl chloride (C6H3ClFNO4S) is characterized by an amide group, 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 protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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