Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 299.94 g/mol gives 1,2-Bis(bromomethyl)-4,5-difluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,2-Bis(bromomethyl)-4,5-difluorobenzene (CAS 915944-27-3), a certified reference material (molecular formula C8H6Br2F2, MW 299.94 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Bis(bromomethyl)-4,5-difluorobenzene (C8H6Br2F2) is characterized by fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,2-Bis(bromomethyl)-4,5-difluorobenzene 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.
