5-Bromo-4-fluoro-2-nitrothiophenol CAS 1807208-90-7

Description

Compared with other compounds in its class, the molecular weight of 252.06 g/mol gives 5-Bromo-4-fluoro-2-nitrothiophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-4-fluoro-2-nitrothiophenol (CAS 1807208-90-7), molecular formula C6H3BrFNO2S and molecular weight 252.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-4-fluoro-2-nitrothiophenol (C6H3BrFNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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.

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.

CATO manufactures 5-Bromo-4-fluoro-2-nitrothiophenol 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.
