Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4',5'-Bis(3,5-diformylphenyl)-3',6'-dimethyl-[1,1':2',1''-terphenyl]-3,3'',5,5''-tetracarbaldehyde.

4',5'-Bis(3,5-diformylphenyl)-3',6'-dimethyl-[1,1':2',1''-terphenyl]-3,3'',5,5''-tetracarbaldehyde (CAS 2764883-80-7) is a high-purity analytical reference standard with the molecular formula C40H26O8 and a molecular weight of 634.63 g/mol.

Based on its molecular formula C40H26O8, 4',5'-Bis(3,5-diformylphenyl)-3',6'-dimethyl-[1,1':2',1''-terphenyl]-3,3'',5,5''-tetracarbaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 634.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
