Description
CATO supplies (R)-2-((4-(2-Chloro-4-fluorophenyl)-2-oxo-2H-chromen-7-yl)oxy)propanoic acid (CAS 2304622-97-5), a certified reference material (molecular formula C18H12ClFO5, MW 362.74 g/mol) for analytical method development and quality control.
The molecular framework of (R)-2-((4-(2-Chloro-4-fluorophenyl)-2-oxo-2H-chromen-7-yl)oxy)propanoic acid (C18H12ClFO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
CATO manufactures (R)-2-((4-(2-Chloro-4-fluorophenyl)-2-oxo-2H-chromen-7-yl)oxy)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
