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 Benzyltriphenylphosphonium 4-(1,1,1,3,3,3-hexafluoro-2-(4-hydroxyphenyl)propan-2-yl)phenolate.
CATO supplies Benzyltriphenylphosphonium 4-(1,1,1,3,3,3-hexafluoro-2-(4-hydroxyphenyl)propan-2-yl)phenolate (CAS 75768-65-9), a certified reference material (molecular formula C25H22PC15H9F6O2, MW 688.65 g/mol) for analytical method development and quality control.
Structurally, Benzyltriphenylphosphonium 4-(1,1,1,3,3,3-hexafluoro-2-(4-hydroxyphenyl)propan-2-yl)phenolate (C25H22PC15H9F6O2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 22.5, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 688.65 g/mol, it falls into the 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.
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.
