Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4''-Dibromo-4',5'-bis(4-bromophenyl)-1,1':2',1''-terphenyl.
4,4''-Dibromo-4',5'-bis(4-bromophenyl)-1,1':2',1''-terphenyl (CAS 1347702-48-0), molecular formula C30H18Br4 and molecular weight 698.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4''-Dibromo-4',5'-bis(4-bromophenyl)-1,1':2',1''-terphenyl (C30H18Br4) is characterized by bromine substitution, a polycyclic aromatic 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
