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 Cyclobis(paraquat-1,4-phenylene) Tetrakis(hexafluorophosphate).
Cyclobis(paraquat-1,4-phenylene) Tetrakis(hexafluorophosphate) (CAS 117271-77-9) is a high-purity analytical reference standard with the molecular formula C36H32N4F6P and a molecular weight of 665.64 g/mol.
Structurally, Cyclobis(paraquat-1,4-phenylene) Tetrakis(hexafluorophosphate) (C36H32N4F6P) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 665.64 g/mol, it falls into the high-molecular-weight range. 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.
