Chemical Structure
Description
The occurrence of 5'-(4-Amino-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro-[1,1':3',1''-terphenyl]-4,4''-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5'-(4-Amino-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro-[1,1':3',1''-terphenyl]-4,4''-diamine (CAS 2750241-87-1), molecular formula C24H15F6N3 and molecular weight 459.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 5'-(4-Amino-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro-[1,1':3',1''-terphenyl]-4,4''-diamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 459.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
