Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.99 g/mol gives Pentafluorobenzyl Bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pentafluorobenzyl Bromide (CAS 1765-40-8) is a high-purity analytical reference standard with the molecular formula C7H2BrF5 and a molecular weight of 260.99 g/mol.
Pentafluorobenzyl Bromide (C7H2BrF5) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Pentafluorobenzyl 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.
