Chemical Structure
Description
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.
Sodium 3-Chloro-2-hydroxypropanesulfonate (CAS 126-83-0), molecular formula C3H6ClO4SNa and molecular weight 196.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution, Sodium 3-Chloro-2-hydroxypropanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.58 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.
