Chemical Structure
Description
The occurrence of 3-([1,1'-Biphenyl]-4-yl(phenyl)phosphino)benzoic acid is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-([1,1'-Biphenyl]-4-yl(phenyl)phosphino)benzoic acid (CAS 62350-80-5) is a high-purity analytical reference standard with the molecular formula C25H19O2P and a molecular weight of 382.39 g/mol.
The molecular framework of 3-([1,1'-Biphenyl]-4-yl(phenyl)phosphino)benzoic acid (C25H19O2P) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. 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.
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.
