2-(2,6-Dibromophenoxy)ethane-1-sulfonyl chloride CAS 1342261-88-4

Description

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.

2-(2,6-Dibromophenoxy)ethane-1-sulfonyl chloride (CAS 1342261-88-4), molecular formula C8H7Br2ClO3S and molecular weight 378.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(2,6-Dibromophenoxy)ethane-1-sulfonyl chloride (C8H7Br2ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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 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).

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.
