Chemical Structure
Description
As a certified reference material (CRM), 1,1'-(Bromomethylene)Bis[2,3,4,5,6-Pentafluorobenzene] 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.
1,1'-(Bromomethylene)Bis[2,3,4,5,6-Pentafluorobenzene] (CAS 5736-49-2) is a high-purity analytical reference standard with the molecular formula C13HBrF10 and a molecular weight of 427.04 g/mol.
The molecular framework of 1,1'-(Bromomethylene)Bis[2,3,4,5,6-Pentafluorobenzene] (C13HBrF10) is characterized by fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
