3-[3-(4-ethoxyphenyl)-1,2,4-oxadiazol-5-yl]propanoic acid CAS 500026-39-1

Description

The occurrence of 3-[3-(4-ethoxyphenyl)-1,2,4-oxadiazol-5-yl]propanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-[3-(4-ethoxyphenyl)-1,2,4-oxadiazol-5-yl]propanoic acid (CAS 500026-39-1), molecular formula C13H14N2O4 and molecular weight 262.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-[3-(4-ethoxyphenyl)-1,2,4-oxadiazol-5-yl]propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 3-[3-(4-ethoxyphenyl)-1,2,4-oxadiazol-5-yl]propanoic 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.
