Description

Compared with other compounds in its class, the molecular weight of 302.14 g/mol gives Ethyl 2-bromo-4-hydroxythieno[2,3-b]pyridine-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-bromo-4-hydroxythieno[2,3-b]pyridine-5-carboxylate (CAS 55503-18-9) is a high-purity analytical reference standard with the molecular formula C10H8BrNO3S and a molecular weight of 302.14 g/mol.

The molecular framework of Ethyl 2-bromo-4-hydroxythieno[2,3-b]pyridine-5-carboxylate (C10H8BrNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
