Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.19 g/mol gives 1-(Difluoro(2-fluorophenyl)methyl)-2,4-difluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(Difluoro(2-fluorophenyl)methyl)-2,4-difluorobenzene (CAS 1374659-23-0), a certified reference material (molecular formula C13H7F5, MW 258.19 g/mol) for analytical method development and quality control.
1-(Difluoro(2-fluorophenyl)methyl)-2,4-difluorobenzene (C13H7F5) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
