Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Chlorobenzyl)triphenylphosphonium tetrafluoroborate.
CATO supplies (4-Chlorobenzyl)triphenylphosphonium tetrafluoroborate (CAS 97559-21-2), a certified reference material (molecular formula C25H21ClPBF4, MW 474.67 g/mol) for analytical method development and quality control.
Structurally, (4-Chlorobenzyl)triphenylphosphonium tetrafluoroborate (C25H21ClPBF4) contains organophosphorus functionality, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 474.67 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (4-Chlorobenzyl)triphenylphosphonium tetrafluoroborate 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.
