Chemical Structure
Description
The occurrence of 4-(2-Chloroethyl)-1,3,2-dioxathiolane 2-oxide is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(2-Chloroethyl)-1,3,2-dioxathiolane 2-oxide (CAS 1378464-10-8), a certified reference material (molecular formula C4H7ClO3S, MW 170.61 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(2-Chloroethyl)-1,3,2-dioxathiolane 2-oxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.61 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.
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.
