Description
As a certified reference material (CRM), 4-(Chloromethyl)-5,7-dihydroxy-2H-chromen-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 4-(Chloromethyl)-5,7-dihydroxy-2H-chromen-2-one (CAS 809234-33-1), a certified reference material (molecular formula C10H7ClO4, MW 226.61 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Chloromethyl)-5,7-dihydroxy-2H-chromen-2-one (C10H7ClO4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
