6-(3-Ethoxyphenyl)indolin-2-one CAS 215433-92-4

Description

Compared with other compounds in its class, the molecular weight of 253.30 g/mol gives 6-(3-Ethoxyphenyl)indolin-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-(3-Ethoxyphenyl)indolin-2-one (CAS 215433-92-4), a certified reference material (molecular formula C16H15NO2, MW 253.30 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 6-(3-Ethoxyphenyl)indolin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
