Description

Compared with other compounds in its class, the molecular weight of 245.06 g/mol gives 6-Chloro-4-(chloromethyl)-7-hydroxy-2H-chromen-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-Chloro-4-(chloromethyl)-7-hydroxy-2H-chromen-2-one (CAS 223420-30-2), a certified reference material (molecular formula C10H6Cl2O3, MW 245.06 g/mol) for analytical method development and quality control.

The molecular framework of 6-Chloro-4-(chloromethyl)-7-hydroxy-2H-chromen-2-one (C10H6Cl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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 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.
