3-(2-Methoxyphenyl)furan-2,5-dione CAS 4664-99-7

Description

Compared with other compounds in its class, the molecular weight of 204.18 g/mol gives 3-(2-Methoxyphenyl)furan-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(2-Methoxyphenyl)furan-2,5-dione (CAS 4664-99-7), molecular formula C11H8O4 and molecular weight 204.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(2-Methoxyphenyl)furan-2,5-dione (C11H8O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
