Chemical Structure
Description
CATO supplies 2,2',3,4,4',6,6'-Heptabromodiphenyl ether (CAS 117948-63-7), a certified reference material (molecular formula C12H3Br7O, MW 722.48 g/mol) for analytical method development and quality control.
Structurally, 2,2',3,4,4',6,6'-Heptabromodiphenyl ether (C12H3Br7O) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 722.48 g/mol, it falls into the high-molecular-weight range. 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.
As a certified reference material (CRM), 2,2',3,4,4',6,6'-Heptabromodiphenyl ether 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.
