Chemical Structure

4-oxopyran-3-carboxamide CAS 127350-47-4 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-oxopyran-3-carboxamide 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).

4-oxopyran-3-carboxamide (CAS 127350-47-4) is a high-purity analytical reference standard with the molecular formula C6H9NO3 and a molecular weight of 143.14 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
