methyl 6-fluoro-3-methyl-2-oxo-1,3-benzoxazole-5-carboxylate CAS 2387594-83-2

Description

Compared with other compounds in its class, the molecular weight of 231.22 g/mol gives methyl 6-fluoro-3-methyl-2-oxo-1,3-benzoxazole-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies methyl 6-fluoro-3-methyl-2-oxo-1,3-benzoxazole-5-carboxylate (CAS 2387594-83-2), a certified reference material (molecular formula C10H14FNO4, MW 231.22 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, fluorine substitution, methyl 6-fluoro-3-methyl-2-oxo-1,3-benzoxazole-5-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.22 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.
