Fifteen series of homologues of a variety of mono-, di- and trifluorosubstituted alkyl 4”-alkylterphenyl-4-yl carbonates have been synthesized and their mesomorphic properties have been determined From among 95 prepared compounds, 40 pure nematogens have been found, as well as 55 mesogens with orthogonal and tilted smectic phases in broad temperature ranges. The type and combination of the LC phase strongly depend on the position and number of the fluorine atoms. Phys. properties and correlations between the mol. core fluorosubstitution, the length of the terminal chains and the type and sequence of the liquid crystalline phases, have been determined The compounds are useful for the formulation of nematic mixtures as well as ferroelec. ones. In the experiment, the researchers used many compounds, for example, Chloroformicacidn-nonylester (cas: 57045-82-6Quality Control of Chloroformicacidn-nonylester).
Chloroformicacidn-nonylester (cas: 57045-82-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Quality Control of Chloroformicacidn-nonylester
