Chemical Structure

3-Ethoxy-4-fluoro-5-(methylthio)benzoic acid CAS 2624417-93-0 chemical structure

Description

CATO manufactures 3-Ethoxy-4-fluoro-5-(methylthio)benzoic acid 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.

3-Ethoxy-4-fluoro-5-(methylthio)benzoic acid (CAS 2624417-93-0) is a high-purity analytical reference standard with the molecular formula C10H11FO3S and a molecular weight of 230.26 g/mol.

3-Ethoxy-4-fluoro-5-(methylthio)benzoic acid (C10H11FO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
