Description

(S)-2-(2'-(bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphanyl)-[1,1'-biphenyl]-2-yl)-4-phenyl-4,5-dihydrooxazole (CAS 1198791-48-8), molecular formula C51H62NO3P and molecular weight 768.02 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-2-(2'-(bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphanyl)-[1,1'-biphenyl]-2-yl)-4-phenyl-4,5-dihydrooxazole (C51H62NO3P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures (S)-2-(2'-(bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphanyl)-[1,1'-biphenyl]-2-yl)-4-phenyl-4,5-dihydrooxazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
