Chemical Structure

3-Ethyl-1-(methylsulfonyl)indoline CAS 591219-80-6 chemical structure

Description

The occurrence of 3-Ethyl-1-(methylsulfonyl)indoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Ethyl-1-(methylsulfonyl)indoline (CAS 591219-80-6), molecular formula C11H15NO2S and molecular weight 225.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H15NO2S, 3-Ethyl-1-(methylsulfonyl)indoline contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
