Description

Compared with other compounds in its class, the molecular weight of 206.65 g/mol gives 4-Chlorobenzene-sulfonmethyl-ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chlorobenzene-sulfonmethyl-ester (CAS 15481-45-5) is a high-purity analytical reference standard with the molecular formula C7H7ClO3S and a molecular weight of 206.65 g/mol.

Structurally, 4-Chlorobenzene-sulfonmethyl-ester (C7H7ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 206.65 g/mol, it falls into the medium-molecular-weight range. 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.
