Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3'',5,5''-Tetrabromo-5'-(3,5-dibromophenyl)-1,1':3',1''-terphenyl.
3,3'',5,5''-Tetrabromo-5'-(3,5-dibromophenyl)-1,1':3',1''-terphenyl (CAS 29102-67-8) is a high-purity analytical reference standard with the molecular formula C24H12Br6 and a molecular weight of 779.78 g/mol.
Structurally, 3,3'',5,5''-Tetrabromo-5'-(3,5-dibromophenyl)-1,1':3',1''-terphenyl (C24H12Br6) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 779.78 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3,3'',5,5''-Tetrabromo-5'-(3,5-dibromophenyl)-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.
