1,3-Dicyclohexylurea (cas: 2387-23-7) 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. 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.Name: 1,3-Dicyclohexylurea

Antioxidant and angiotensin-I converting enzyme inhibitory activities of phenolic extracts and fractions derived from three phenolic-rich legume varieties was written by Zhang, Yan;Pechan, Tibor;Chang, Sam K. C.. And the article was included in Journal of Functional Foods in 2018.Name: 1,3-Dicyclohexylurea This article mentions the following:

Lentil, black soybean and black turtle bean are commonly consumed legumes of different genera, containing high phenolic contents, which are effective antioxidants and angiotensin-I converting enzyme (ACE) inhibitors. However, these legumes’ phenolic compositions and ACE inhibition ability have not been compared. Crude water extract (CE) was semi-purified (SPE) and fractionated using column chromatog. Results showed that purification and fractionation could substantially increase phenolic contents and antioxidant capacities. Heating and variety had great effect on phenolic substances, antioxidant potential and mass yield of extracts and fractions. Only crude extracts showed potent ACE inhibitory activity. Black turtle bean’s ACE inhibition potential was largely reduced by cooking. The order from low to high in terms of ACE inhibitory activity was black turtle bean < lentil < black soybean. Identification and quantification of individual phenolic compounds by UV spectroscopy and LC-MSn anal. confirmed 18, 22, and 14 compounds, resp., for the three legumes. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7Name: 1,3-Dicyclohexylurea).
