Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.05 g/mol gives 2-Fluoro-4-methylbenzyl bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Fluoro-4-methylbenzyl bromide (CAS 118745-63-4), a certified reference material (molecular formula C8H8BrF, MW 203.05 g/mol) for analytical method development and quality control.
2-Fluoro-4-methylbenzyl bromide (C8H8BrF) contains fluorine/bromine 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. 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.
