Chemical Structure
Description
As a certified reference material (CRM), (5-Ethyl-1,2,4-oxadiazol-3-yl)methanamine 4-methylbenzenesulfonate 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.
(5-Ethyl-1,2,4-oxadiazol-3-yl)methanamine 4-methylbenzenesulfonate (CAS 2089650-08-6), molecular formula C7H8O3SC5H9N3O and molecular weight 299.35 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Ethyl-1,2,4-oxadiazol-3-yl)methanamine 4-methylbenzenesulfonate (C7H8O3SC5H9N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
