Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, methyl 5-methoxy-2,3-dihydrobenzofuran-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.21 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.
methyl 5-methoxy-2,3-dihydrobenzofuran-4-carboxylate (CAS 156297-82-4) is a high-purity analytical reference standard with the molecular formula C11H12O4 and a molecular weight of 208.21 g/mol.
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.
