Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 287.14 g/mol gives 3-(2-Chloro-4-fluorophenoxy)propane-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(2-Chloro-4-fluorophenoxy)propane-1-sulfonyl chloride (CAS 1340129-74-9) is a high-purity analytical reference standard with the molecular formula C9H9Cl2FO3S and a molecular weight of 287.14 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 3-(2-Chloro-4-fluorophenoxy)propane-1-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
