7-Methoxy-1-benzofuran-4-carboxylic acid CAS 33401-32-0

Description

Compared with other compounds in its class, the molecular weight of 192.17 g/mol gives 7-Methoxy-1-benzofuran-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 7-Methoxy-1-benzofuran-4-carboxylic acid (CAS 33401-32-0), a certified reference material (molecular formula C10H8O4, MW 192.17 g/mol) for analytical method development and quality control.

7-Methoxy-1-benzofuran-4-carboxylic acid (C10H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
