1-Ethyl-4-methylindoline CAS 86911-83-3

Description

Compared with other compounds in its class, the molecular weight of 161.24 g/mol gives 1-Ethyl-4-methylindoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Ethyl-4-methylindoline (CAS 86911-83-3) is a high-purity analytical reference standard with the molecular formula C11H15N and a molecular weight of 161.24 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Ethyl-4-methylindoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 161.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
