Chemical Structure

3-(1H-Pyrrol-1-yl)indolin-2-one CAS 16176-35-5 chemical structure

Description

Based on its molecular formula C12H10N2O, 3-(1H-Pyrrol-1-yl)indolin-2-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.22 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.

3-(1H-Pyrrol-1-yl)indolin-2-one (CAS 16176-35-5) is a high-purity analytical reference standard with the molecular formula C12H10N2O and a molecular weight of 198.22 g/mol.

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.
