Description
As a certified reference material (CRM), 2,2''-Dibromo-5'-(2-bromophenyl)-1,1':3',1''-terphenyl 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.
2,2''-Dibromo-5'-(2-bromophenyl)-1,1':3',1''-terphenyl (CAS 380626-56-2), molecular formula C24H15Br3 and molecular weight 543.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, a polycyclic aromatic system, 2,2''-Dibromo-5'-(2-bromophenyl)-1,1':3',1''-terphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 543.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
