Compared with other compounds in its class, the molecular weight of 242.31 g/mol gives ethyl 6-methoxy-3-methyl-benzofuran-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies ethyl 6-methoxy-3-methyl-benzofuran-2-carboxylate (CAS 53724-96-2), a certified reference material (molecular formula C13H22O4, MW 242.31 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, ethyl 6-methoxy-3-methyl-benzofuran-2-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
