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 1,4-Bis(bis(3,5-bis(trifluoromethyl)phenyl)phosphino)butane.
1,4-Bis(bis(3,5-bis(trifluoromethyl)phenyl)phosphino)butane (CAS 220185-41-1) is a high-purity analytical reference standard with the molecular formula C36H20F24P2 and a molecular weight of 970.45 g/mol.
1,4-Bis(bis(3,5-bis(trifluoromethyl)phenyl)phosphino)butane (C36H20F24P2) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 1,4-Bis(bis(3,5-bis(trifluoromethyl)phenyl)phosphino)butane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
