Chemical Structure
Description
As a certified reference material (CRM), Sodium 2-chloroethanesulfonatehydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Sodium 2-chloroethanesulfonatehydrate (CAS 1089719-72-1), molecular formula C2H5ClO3SNaH2O and molecular weight 185.57 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 2-chloroethanesulfonatehydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.57 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.
