Chemical Structure

8-Methyl-3-[(2-m-tolyl-ethylamino)-methyl]-1H-quinolin-2-one CAS 551945-42-7 chemical structure

Description

Based on its molecular formula C20H22N2O, 8-Methyl-3-[(2-m-tolyl-ethylamino)-methyl]-1H-quinolin-2-one 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 306.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

8-Methyl-3-[(2-m-tolyl-ethylamino)-methyl]-1H-quinolin-2-one (CAS 551945-42-7) is a high-purity analytical reference standard with the molecular formula C20H22N2O and a molecular weight of 306.40 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
