Chemical Structure
Description
Dimethyl 4-ethylisoxazole-3,5-bis(carbimidate) (CAS 749216-94-2) is a high-purity analytical reference standard with the molecular formula C9H13N3O3 and a molecular weight of 211.22 g/mol.
Dimethyl 4-ethylisoxazole-3,5-bis(carbimidate) (C9H13N3O3) 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), Dimethyl 4-ethylisoxazole-3,5-bis(carbimidate) 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.
