Ethyl 5-propylthiophene-2-carboxylate CAS 1256286-41-5 chemical structure

Description

CATO manufactures Ethyl 5-propylthiophene-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Ethyl 5-propylthiophene-2-carboxylate (CAS 1256286-41-5) is a high-purity analytical reference standard with the molecular formula C10H14O2S and a molecular weight of 198.28 g/mol.

Structurally, Ethyl 5-propylthiophene-2-carboxylate (C10H14O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 198.28 g/mol, it falls into the medium-molecular-weight range. 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.
