4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.Category: esters-buliding-blocks

Li, Z.; An, Z.; Zheng, Y.; Feng, K. published an article on January 31 ,1998. The article was titled 《Compatibility study of a multi-component TN liquid crystal mixture and a multi-component cholesteric liquid crystal mixture by DSC》, and you may find the article in Molecular Crystals and Liquid Crystals Science and Technology.Category: esters-buliding-blocks The information in the text is summarized as follows:

The phase transition curves of multi-component TN liquid crystal mixture (TN88-1) and a multi-component cholesteric liquid crystal mixture (Ch88-2) were plotted by a differential scanning calorimeter. The phase transition temperature and phase transition heat were obtained from the DSC curves. The components of TN88-1 are compatible and they can form a stable mixture with CB15 chiral liquid crystal. The components of Ch88-2 are not compatible and Poly (MMA-BMA) can greatly improve their compatibility. The experimental process involved the reaction of 4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9Category: esters-buliding-blocks)

4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9) belongs to esters. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. Category: esters-buliding-blocks

Osman, Maged A. published an article in Zeitschrift fuer Naturforschung, Teil A: Physik, Physikalische Chemie, Kosmophysik. The title of the article was 《Molecular structure and mesomorphic properties of thermotropic liquid crystals. II. Terminal substituents》.Category: esters-buliding-blocks The author mentioned the following in the article:

The effect of terminal polar nonpolar substituents on the thermodn. stability of the mesophase is discussed. Mesomeric and steric effects influence the packing of the mols. and consequently the clearing point. It is necessary to consider the effect of substituents in connection with the nature of the rigid core. The influence of mol. association and conformational equilibrium on the stability of the mesophase is described. Isolated electron densities lead to repulsions between neighboring mols., thus destabilizing the mesophase and the layered structure if present.4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9Category: esters-buliding-blocks) was used in this study.
