Chemical Structure
Description
(3,5-difluorobenzyl)zinc(II) bromide 3,5-Difluorobenzylzinc bromide 308796-30-7 (C7H11BrF2Zn) contains a salt form, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
(3,5-difluorobenzyl)zinc(II) bromide 3,5-Difluorobenzylzinc bromide 308796-30-7 (CAS 308796-30-7), molecular formula C7H11BrF2Zn and molecular weight 278.47 g/mol, is a CATO reference standard with documented purity and traceability.
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.
