Chemical Structure
Description
4-Fluoro-3-(methoxymethyl)-1-benzothiophene-2-carboxylic acid (CAS 854357-47-4), molecular formula C11H9FO3S and molecular weight 240.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H9FO3S, 4-Fluoro-3-(methoxymethyl)-1-benzothiophene-2-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 4-Fluoro-3-(methoxymethyl)-1-benzothiophene-2-carboxylic 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.
