Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies n-(2-Hydroxyethyl)-2,3,5,6-tetramethylbenzenesulfonamide (CAS 920116-00-3), a certified reference material (molecular formula C12H19NO3S, MW 257.35 g/mol) for analytical method development and quality control.
n-(2-Hydroxyethyl)-2,3,5,6-tetramethylbenzenesulfonamide (C12H19NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), n-(2-Hydroxyethyl)-2,3,5,6-tetramethylbenzenesulfonamide 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.
