Chemical Structure

5-fluoro-4-methyl-2-nitrobenzene-1-sulfonyl chloride CAS 1804051-34-0 chemical structure

Description

CATO manufactures 5-fluoro-4-methyl-2-nitrobenzene-1-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

5-fluoro-4-methyl-2-nitrobenzene-1-sulfonyl chloride (CAS 1804051-34-0) is a high-purity analytical reference standard with the molecular formula C7H5ClFNO4S and a molecular weight of 253.64 g/mol.

The molecular framework of 5-fluoro-4-methyl-2-nitrobenzene-1-sulfonyl chloride (C7H5ClFNO4S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
