Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.56 g/mol gives 2-(Chloromethoxy)-1,4-difluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(Chloromethoxy)-1,4-difluorobenzene (CAS 1542044-70-1), a certified reference material (molecular formula C7H5ClF2O, MW 178.56 g/mol) for analytical method development and quality control.
2-(Chloromethoxy)-1,4-difluorobenzene (C7H5ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
