5-(2-Methyl-pyridin-4-yl)-thiophene-2-carboxylic acid ethyl ester (CAS 1187168-63-3) is a high-purity analytical reference standard with the molecular formula C13H13NO2S and a molecular weight of 247.31 g/mol.
The molecular framework of 5-(2-Methyl-pyridin-4-yl)-thiophene-2-carboxylic acid ethyl ester (C13H13NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
