3-(tert-Butyl)-3-hydroxy-2-methyl-5-phenylisoindolin-1-one CAS 39563-83-2

Description

The occurrence of 3-(tert-Butyl)-3-hydroxy-2-methyl-5-phenylisoindolin-1-one 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.

CATO supplies 3-(tert-Butyl)-3-hydroxy-2-methyl-5-phenylisoindolin-1-one (CAS 39563-83-2), a certified reference material (molecular formula C19H21NO2, MW 295.38 g/mol) for analytical method development and quality control.

The molecular framework of 3-(tert-Butyl)-3-hydroxy-2-methyl-5-phenylisoindolin-1-one (C19H21NO2) 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. 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.

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.
