Methyl 3-(isoxazol-3-ylmethyl)-2-oxo-2,3-dihydrobenzo[d]oxazole-5-carboxylate CAS 1020243-01-9

Description

Compared with other compounds in its class, the molecular weight of 274.23 g/mol gives Methyl 3-(isoxazol-3-ylmethyl)-2-oxo-2,3-dihydrobenzo[d]oxazole-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 3-(isoxazol-3-ylmethyl)-2-oxo-2,3-dihydrobenzo[d]oxazole-5-carboxylate (CAS 1020243-01-9), a certified reference material (molecular formula C13H10N2O5, MW 274.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Methyl 3-(isoxazol-3-ylmethyl)-2-oxo-2,3-dihydrobenzo[d]oxazole-5-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
