Description

Compared with other compounds in its class, the molecular weight of 295.18 g/mol gives 5-Chloro-2-(cyclopentyloxy)benzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-2-(cyclopentyloxy)benzene-1-sulfonyl chloride (CAS 1245534-96-6), molecular formula C11H12Cl2O3S and molecular weight 295.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 5-Chloro-2-(cyclopentyloxy)benzene-1-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
