Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 350.04 g/mol gives 4-(Bromomethyl)-5-(difluoromethyl)-3-(trifluoromethoxy)picolinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Bromomethyl)-5-(difluoromethyl)-3-(trifluoromethoxy)picolinic acid (CAS 1806765-34-3), a certified reference material (molecular formula C9H5BrF5NO3, MW 350.04 g/mol) for analytical method development and quality control.
4-(Bromomethyl)-5-(difluoromethyl)-3-(trifluoromethoxy)picolinic acid (C9H5BrF5NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, 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.
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.
