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 tetraphenylborate.
Benzyltriphenylphosphonium tetraphenylborate (CAS 16893-58-6) is a high-purity analytical reference standard with the molecular formula C25H22PC24H20B and a molecular weight of 672.66 g/mol.
The molecular framework of Benzyltriphenylphosphonium tetraphenylborate (C25H22PC24H20B) is characterized by organophosphorus functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Benzyltriphenylphosphonium tetraphenylborate 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.
