Chemical Structure
Description
2-(2-Oxo-1,3-oxazolidin-3-yl)ethane-1-sulfonyl chloride (CAS 1935635-92-9), molecular formula C5H8ClNO4S and molecular weight 213.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution, 2-(2-Oxo-1,3-oxazolidin-3-yl)ethane-1-sulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.64 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.
