Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Bromo-4,6-difluoro-3'-methyl-1,1'-biphenyl (CAS 1071866-13-1), a certified reference material (molecular formula C13H9BrF2, MW 283.11 g/mol) for analytical method development and quality control.
2-Bromo-4,6-difluoro-3'-methyl-1,1'-biphenyl (C13H9BrF2) contains fluorine/bromine 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).
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.
