Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 148.16 g/mol gives 4-Methoxybenzofuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Methoxybenzofuran (CAS 18014-96-5), a certified reference material (molecular formula C9H8O2, MW 148.16 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Methoxybenzofuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
