ethyl 4-hydroxythiophene-2-carboxylate CAS 133019-68-8

Description

Compared with other compounds in its class, the molecular weight of 172.20 g/mol gives ethyl 4-hydroxythiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

ethyl 4-hydroxythiophene-2-carboxylate (CAS 133019-68-8), molecular formula C7H8O3S and molecular weight 172.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, ethyl 4-hydroxythiophene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.20 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).
