Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluoro-3-(phenoxymethyl)-1-benzothiophene-2-carboxylic acid.
4-Fluoro-3-(phenoxymethyl)-1-benzothiophene-2-carboxylic acid (CAS 929974-17-4) is a high-purity analytical reference standard with the molecular formula C16H11FO3S and a molecular weight of 302.32 g/mol.
The molecular framework of 4-Fluoro-3-(phenoxymethyl)-1-benzothiophene-2-carboxylic acid (C16H11FO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Fluoro-3-(phenoxymethyl)-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.
