2-chloroprop-2-ene-1-sulfonyl chloride CAS 40644-59-5

Description

Compared with other compounds in its class, the molecular weight of 175.03 g/mol gives 2-chloroprop-2-ene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-chloroprop-2-ene-1-sulfonyl chloride (CAS 40644-59-5) is a high-purity analytical reference standard with the molecular formula C3H4Cl2O2S and a molecular weight of 175.03 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-chloroprop-2-ene-1-sulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.03 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
