1,3-Dicyclohexylurea (cas: 2387-23-7) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Application of 2387-23-7

Mesomorphic and geometrical orientation study of the relative position of fluorine atom in some thermotropic liquid crystal systems was written by Ahmed, H. A.;Hagar, M.;Alhaddad, O. A.. And the article was included in Liquid Crystals in 2020.Application of 2387-23-7 This article mentions the following:

New series of the Schiff base/esters, 4-((2′-or 3′-fluorophenylimino)methyl)phenyl-4”-alkoxy benzoates and 4-((3-fluorophenyl)diazenyl)phenyl 4”-alkoxy benzoates, I [X = C, N; R1 = hexyl, octyl, decyl, etc.; R2 = 2-F, 3-F ] were prepared and their mesophase behavior investigated. The type of the mesophase and its transition temperature were determined by differential scanning calorimetry (DSC) and polarised optical microscopy (POM). The optimized structures of Schiff base/ester and their azo/ester groups were deduced theor. by d. functional theory (DFT). Each group of homologues differed from the other by the position of the fluorine atom on the terminal benzene ring, in addition to laterally neat homologues. Comparative studies revealed that the position and orientation of the lateral fluorine atom as well as the type of the linking core not only affected the melting temperature but also the mesophase stability. DFT results showed that the type and stability of the mesophase could be illustrated in the terms of calculated dipole moment, polarisability, thermal energy and mol. electrostatic potential. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7Application of 2387-23-7).
