Chemical Structure
Description
Based on its molecular formula C16H22N2O2S, (2R)-2-[(3,3-dimethyl-2,4-dihydroisoquinolin-1-ylidene)ammonio]-4-(methylthio)butanoate (2R)-2-[(3,3-dimethyl-2,4-dihydroisoquinolin-1-ylidene)azaniumyl]-4-methylsulfanyl-butanoate 187884-93-1 A813182 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 306.42 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.
