Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 6-(2-furyl)-3-phenylisoxaZolo[5,4-b]pyridine-4-carboxylate.
CATO supplies methyl 6-(2-furyl)-3-phenylisoxaZolo[5,4-b]pyridine-4-carboxylate (CAS 938022-16-3), a certified reference material (molecular formula C18H12N2O4, MW 320.30 g/mol) for analytical method development and quality control.
Structurally, methyl 6-(2-furyl)-3-phenylisoxaZolo[5,4-b]pyridine-4-carboxylate (C18H12N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 320.30 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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), methyl 6-(2-furyl)-3-phenylisoxaZolo[5,4-b]pyridine-4-carboxylate 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.
