Chemical Structure

6,8-Dichloro-3-(furan-2-carbonyl)-2-phenyl-4H-chromen-4-one CAS 673857-32-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 385.20 g/mol gives 6,8-Dichloro-3-(furan-2-carbonyl)-2-phenyl-4H-chromen-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6,8-Dichloro-3-(furan-2-carbonyl)-2-phenyl-4H-chromen-4-one (CAS 673857-32-4) is a high-purity analytical reference standard with the molecular formula C20H10Cl2O4 and a molecular weight of 385.20 g/mol.

The molecular framework of 6,8-Dichloro-3-(furan-2-carbonyl)-2-phenyl-4H-chromen-4-one (C20H10Cl2O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
