Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Methyl 3-(5-methylisoxazole-4-carboxamido)benzoate (CAS 724430-95-9), a certified reference material (molecular formula C13H12N2O4, MW 260.25 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-(5-methylisoxazole-4-carboxamido)benzoate (C13H12N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Methyl 3-(5-methylisoxazole-4-carboxamido)benzoate 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.
