Chemical Structure
Description
3-(3-Ethoxyisoxazol-5-yl)propanoic acid (CAS 878712-11-9) is a high-purity analytical reference standard with the molecular formula C8H11NO4 and a molecular weight of 185.18 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-(3-Ethoxyisoxazol-5-yl)propanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.18 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
