3-(1-Oxoisoindolin-2-yl)-3-(o-tolyl)propanoic acid CAS 478249-82-0

Description

The occurrence of 3-(1-Oxoisoindolin-2-yl)-3-(o-tolyl)propanoic acid 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-(1-Oxoisoindolin-2-yl)-3-(o-tolyl)propanoic acid (CAS 478249-82-0), a certified reference material (molecular formula C18H17NO3, MW 295.33 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H17NO3, 3-(1-Oxoisoindolin-2-yl)-3-(o-tolyl)propanoic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
