Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 554.57 g/mol gives Tri([1,1'-biphenyl]-2-yl) phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tri([1,1'-biphenyl]-2-yl) phosphate (CAS 132-28-5) is a high-purity analytical reference standard with the molecular formula C36H27O4P and a molecular weight of 554.57 g/mol.
The molecular framework of Tri([1,1'-biphenyl]-2-yl) phosphate (C36H27O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
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), Tri([1,1'-biphenyl]-2-yl) phosphate 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.
