(Z)-4-(Furan-2-ylmethylene)-2-methoxy-2H-pyran-3(4H)-one CAS 88874-84-4

Description

The occurrence of (Z)-4-(Furan-2-ylmethylene)-2-methoxy-2H-pyran-3(4H)-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(Z)-4-(Furan-2-ylmethylene)-2-methoxy-2H-pyran-3(4H)-one (CAS 88874-84-4), molecular formula C11H10O4 and molecular weight 206.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H10O4, (Z)-4-(Furan-2-ylmethylene)-2-methoxy-2H-pyran-3(4H)-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
