Chemical Structure
Description
N-Chlorotaurine, sodium salt (CAS 144557-26-6), molecular formula C2H5ClNO3SNa and molecular weight 181.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, an amide group, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution, N-Chlorotaurine, sodium salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.57 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.
CATO manufactures N-Chlorotaurine, sodium salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
