Chemical Structure
Description
Structurally, Sodium 2-chloro-1-hydroxyethane-1-sulfonate (C2H4ClO4SNa) contains a salt form, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 182.55 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Sodium 2-chloro-1-hydroxyethane-1-sulfonate (CAS 13064-50-1), molecular formula C2H4ClO4SNa and molecular weight 182.55 g/mol, is a CATO reference standard with documented purity and traceability.
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.
