ethyl 4-(chlorosulfonyl)-3-fluorobenzoate CAS 1063734-43-9

Description

The molecular framework of ethyl 4-(chlorosulfonyl)-3-fluorobenzoate (C9H8ClFO4S) is characterized by 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 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).

CATO supplies ethyl 4-(chlorosulfonyl)-3-fluorobenzoate (CAS 1063734-43-9), a certified reference material (molecular formula C9H8ClFO4S, MW 266.67 g/mol) for analytical method development and quality control.

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.
