Chemical Structure
Description
The molecular framework of Methyl 3-((3,4-dichlorobenzyl)oxy)thieno[2,3-b]pyridine-2-carboxylate (C16H11Cl2NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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).
Methyl 3-((3,4-dichlorobenzyl)oxy)thieno[2,3-b]pyridine-2-carboxylate (CAS 338419-32-2), molecular formula C16H11Cl2NO3S and molecular weight 368.23 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
