Description

Compared with other compounds in its class, the molecular weight of 246.22 g/mol gives 4-[(5-methyl-1,2-oxazole-4-)amido]benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-[(5-methyl-1,2-oxazole-4-)amido]benzoic acid (CAS 67387-52-4), molecular formula C12H10N2O4 and molecular weight 246.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-[(5-methyl-1,2-oxazole-4-)amido]benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), 4-[(5-methyl-1,2-oxazole-4-)amido]benzoic acid 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.
