Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 213.06 g/mol gives 2,3-Difluorobenzyl bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,3-Difluorobenzyl bromide (CAS 113211-94-2), a certified reference material (molecular formula C7H11BrF2, MW 213.06 g/mol) for analytical method development and quality control.
Owing to fluorine/bromine substitution, 2,3-Difluorobenzyl bromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2,3-Difluorobenzyl bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
