Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2',3,4-Trifluoro-4'''-propyl-1,1':4',1'':4'',1'''-quaterphenyl (CAS 1908465-88-2), molecular formula C27H21F3 and molecular weight 402.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2',3,4-Trifluoro-4'''-propyl-1,1':4',1'':4'',1'''-quaterphenyl (C27H21F3) contains fluorine 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 402.45 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
