4',6''-Bis((S)-4-isopropyl-4,5-dihydrooxazol-2-yl)-1,1':3',1'':3'',1'''-quaterphenyl CAS 890933-57-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 528.68 g/mol gives 4',6''-Bis((S)-4-isopropyl-4,5-dihydrooxazol-2-yl)-1,1':3',1'':3'',1'''-quaterphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4',6''-Bis((S)-4-isopropyl-4,5-dihydrooxazol-2-yl)-1,1':3',1'':3'',1'''-quaterphenyl (CAS 890933-57-0) is a high-purity analytical reference standard with the molecular formula C36H36N2O2 and a molecular weight of 528.68 g/mol.

The molecular framework of 4',6''-Bis((S)-4-isopropyl-4,5-dihydrooxazol-2-yl)-1,1':3',1'':3'',1'''-quaterphenyl (C36H36N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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. 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 4',6''-Bis((S)-4-isopropyl-4,5-dihydrooxazol-2-yl)-1,1':3',1'':3'',1'''-quaterphenyl 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.
