In this paper we present the results of the investigations of liquid crystalline (LC) compounds with pos. dielec. anisotropy. The anal. of the properties of polar mesomorphic compounds and the electrooptical and dynamic parameters of the LC compositions based on them has shown that the polar liquid crystalline 1,3,2- dioxaborinane derivatives have several advantages in comparison with other analogous polar compounds They are characterized by a low formation temperature and a wide temperature range of the nematic phase, and allow preparation of liquid crystalline compositions with a low threshold voltage and shorter switching times. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-hydroxybenzonitrile (cas: 82380-17-4HPLC of Formula: 82380-17-4).
2-Bromo-4-hydroxybenzonitrile (cas: 82380-17-4) belongs to nitriles. Nitrile carbon shifts are in the range of 115–125 ppm whereas in isonitriles the shifts are around 155–165 ppm. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.HPLC of Formula: 82380-17-4
