CATO supplies Methyl 4-[2-(4-chloro-2-methylphenoxy)-2,2-difluoroacetamido]benzoate (CAS 339030-58-9), a certified reference material (molecular formula C17H14ClF2NO4, MW 369.75 g/mol) for analytical method development and quality control.
Methyl 4-[2-(4-chloro-2-methylphenoxy)-2,2-difluoroacetamido]benzoate (C17H14ClF2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Methyl 4-[2-(4-chloro-2-methylphenoxy)-2,2-difluoroacetamido]benzoate 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.
