Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-(tert-Butyl)phenyl)diphenylsulfonium bromide.
(4-(tert-Butyl)phenyl)diphenylsulfonium bromide (CAS 258872-06-9) is a high-purity analytical reference standard with the molecular formula C22H23SBr and a molecular weight of 399.39 g/mol.
The molecular framework of (4-(tert-Butyl)phenyl)diphenylsulfonium bromide (C22H23SBr) is characterized by sulfur-containing functionality, bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(tert-Butyl)phenyl)diphenylsulfonium bromide 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.
