Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5'-([2,2':6',2''-Terpyridin]-4'-yl)-[1,1':3',1''-terphenyl]-4,4''-dicarboxylic acid.
5'-([2,2':6',2''-Terpyridin]-4'-yl)-[1,1':3',1''-terphenyl]-4,4''-dicarboxylic acid (CAS 2230706-35-9) is a high-purity analytical reference standard with the molecular formula C35H23N3O4 and a molecular weight of 549.57 g/mol.
The molecular framework of 5'-([2,2':6',2''-Terpyridin]-4'-yl)-[1,1':3',1''-terphenyl]-4,4''-dicarboxylic acid (C35H23N3O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
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.
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.
