2,3-Dichlorothiophene-5-sulphonyl chloride CAS 126714-85-0

Description

Compared with other compounds in its class, the molecular weight of 251.54 g/mol gives 2,3-Dichlorothiophene-5-sulphonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3-Dichlorothiophene-5-sulphonyl chloride (CAS 126714-85-0) is a high-purity analytical reference standard with the molecular formula C4HCl3O2S2 and a molecular weight of 251.54 g/mol.

2,3-Dichlorothiophene-5-sulphonyl chloride (C4HCl3O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
