(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Quality Control of (2E,4E)-N-Isobutyldeca-2,4-dienamide

Chemical constituents in Piper longum L. (I) was written by Wu, Xia;Yu, Zhibin;Ye, Yunhua;Zhou, Yawei. And the article was included in Zhongcaoyao in 2008.Quality Control of (2E,4E)-N-Isobutyldeca-2,4-dienamide The following contents are mentioned in the article:

The chem. constituents from in Piper longum L. were separated and purified by column chromatog. with silica gel, RP-C18, Sephadex LH-20, and their structures were identified by ESI-MS, 1H-NMR, and 13C-NMR. Ten compounds were obtained and identified as: piperine (I), Me piperate (II), guineensine (III), phenylpropionic acid (IV), pipercide (V), piperanine (VI), pellitorine (VII), (E)-4-[(2-methylpropyl)amino]-4-oxo-2-butenoic acid (VIII), pipernonaline (IX), and β-sitosterol (X), resp. Compound II, IV, and VIII were isolated from this plant for the first time. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Quality Control of (2E,4E)-N-Isobutyldeca-2,4-dienamide).
