2-Phenyl-3-styryl-5-(p-tolyl)isoxazolidine CAS 120781-95-5

Description

The occurrence of 2-Phenyl-3-styryl-5-(p-tolyl)isoxazolidine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Phenyl-3-styryl-5-(p-tolyl)isoxazolidine (CAS 120781-95-5) is a high-purity analytical reference standard with the molecular formula C24H23NO and a molecular weight of 341.45 g/mol.

The molecular framework of 2-Phenyl-3-styryl-5-(p-tolyl)isoxazolidine (C24H23NO) is characterized by a steroid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
