Chemical Structure
Description
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.
2-(1-Methoxy-1-methylethyl)-benzofuran-5-carboxylic acid methyl ester (CAS 1154060-94-2) is a high-purity analytical reference standard with the molecular formula C14H16O4 and a molecular weight of 248.27 g/mol.
2-(1-Methoxy-1-methylethyl)-benzofuran-5-carboxylic acid methyl ester (C14H16O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, 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).
CATO manufactures 2-(1-Methoxy-1-methylethyl)-benzofuran-5-carboxylic acid methyl ester 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.
