Chemical Structure
Description
CATO supplies N-(Isoxazol-3-yl)isobutyramide (CAS 524934-16-5), a certified reference material (molecular formula C7H10N2O2, MW 154.17 g/mol) for analytical method development and quality control.
N-(Isoxazol-3-yl)isobutyramide (C7H10N2O2) contains an amino-acid-derived structure, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), N-(Isoxazol-3-yl)isobutyramide 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.
