Description
CATO supplies 4-(3-Ethyl-2,3-dihydrobenzo[d]oxazol-2-yl)but-3-enamide (CAS 98045-81-9), a certified reference material (molecular formula C13H16N2O2, MW 232.28 g/mol) for analytical method development and quality control.
4-(3-Ethyl-2,3-dihydrobenzo[d]oxazol-2-yl)but-3-enamide (C13H16N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(3-Ethyl-2,3-dihydrobenzo[d]oxazol-2-yl)but-3-enamide 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.
