3-ethyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid 471246-96-5 Z2106602829 CAS 471246-96-5

Description

As a certified reference material (CRM), 3-ethyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid 471246-96-5 Z2106602829 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.

3-ethyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid 471246-96-5 Z2106602829 (CAS 471246-96-5), molecular formula C6H9NO3 and molecular weight 143.14 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, 3-ethyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid 471246-96-5 Z2106602829 is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.14 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.
