Description
As a certified reference material (CRM), Carbostyril 124 N-Carboxymethyl Methanethiosulfonate 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.
Carbostyril 124 N-Carboxymethyl Methanethiosulfonate (CAS 1076199-73-9), molecular formula C13H14N2O4S2 and molecular weight 326.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Carbostyril 124 N-Carboxymethyl Methanethiosulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
