Chemical Structure

Ethyl Oxazole-5-carboxylate CAS 118994-89-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 141.12 g/mol gives Ethyl Oxazole-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl Oxazole-5-carboxylate (CAS 118994-89-1), molecular formula C6H7NO3 and molecular weight 141.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H7NO3, Ethyl Oxazole-5-carboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 141.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Ethyl Oxazole-5-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.
