Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.63 g/mol gives Ethyl 2-chloroethyl sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-chloroethyl sulfonate (CAS 25372-93-4), molecular formula C4H9ClO3S and molecular weight 172.63 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, Ethyl 2-chloroethyl sulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.63 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
