Chemical Structure

2-Bromo-4-fluorobenzene-1-thiol CAS 773853-92-2 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

2-Bromo-4-fluorobenzene-1-thiol (CAS 773853-92-2), molecular formula C6H4BrFS and molecular weight 207.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-4-fluorobenzene-1-thiol (C6H4BrFS) is characterized by sulfur-containing functionality, fluorine/bromine 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 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.
