(<I>S</I>)-4-tert-butyl-2-[2-(diphenylphosphino)phenyl]-2-oxazoline CAS 148461-16-9 chemical structure

Description

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.

(<I>S</I>)-4-tert-butyl-2-[2-(diphenylphosphino)phenyl]-2-oxazoline (CAS 148461-16-9) is a high-purity analytical reference standard with the molecular formula C25H26NOP and a molecular weight of 387.45 g/mol.

The molecular framework of (<I>S</I>)-4-tert-butyl-2-[2-(diphenylphosphino)phenyl]-2-oxazoline (C25H26NOP) is characterized by a steroid core, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures (<I>S</I>)-4-tert-butyl-2-[2-(diphenylphosphino)phenyl]-2-oxazoline 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.
