Cyclopiperettine, a new amide, was isolated from essential oil of Piper nigrum L. together with ten known compounds, including amides, monoterpenoids, and sesquiterpenoids. The structure of cyclopiperettine was established by 1D- and 2D- NMR and GC-MS techniques. Known compounds were identified as α-humulene, β-caryophyllene, caryophyllenol-II, β-elemene, elemol, 1-terpinen-4-ol, nerolidol, pellitorine, piperolein B and piperine. The crude oil and isolated compounds exhibited no antimicrobial activity against seven microbial strains up to 20 μg/mL. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Product Details of 18836-52-7).
(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Product Details of 18836-52-7
