One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine. 4224-70-8, formula is C6H11BrO2, Name is 6-Bromohexanoic acid, Safety of 6-Bromohexanoic acid
Nayak, Rashmi Ashwathama;Bhat, Sachin A.;Rao, D. S. Shankar;Yelamaggad, C. V. research published 《 Wide thermal range, exclusive occurrence of technically significant chiral nematic phase: synthesis and mesomorphism of cholesterol-based non-symmetric dimers》, the research content is summarized as follows. Fifteen new non-sym. chiral dimers belonging to three different series have been synthesized and evaluated for their mesomorphic properties. They were formed by interlinking cholesterol with salicylaldimine (SAN) cores (with reverse imine groups) via an ω-oxyalkanoyloxy spacer. Within a series, the length of the terminal n-alkoxy tails had been varied for a fixed even-parity spacer. Three even-parity spacers such as 4-oxybutanoyloxy, 6-oxyhexanoyloxy and 8-oxyoctanoyloxy have been used to join two cores, whereas the terminal tails such as n-butyloxy, n-hexyloxy, n-octyloxy, n-decyloxy and n-dodecyloxy chains have been attached to the SAN core. Microscopic and calorimetric exptl. results show that all the dimers behave identically exhibiting the chiral nematic (N*) phase solely, which was authenticated by powder X-ray diffraction studies carried out on some selected samples. In the vast majority of the cases,the phase was thermodynamically stable, and while cooling, it exists over a wide thermal range covering room temperature(RT)due to supercooling. Finding was notable given the fact that the N* phase possesses technol. significant optical properties. At RT, the N* phase displayed one of the iridescent colors characteristically caused by interference and diffraction of the reflected and scattered light. A comparative study reveals that the lengths of both the terminal chain and central spacer influence the clearing temperature of the dimers, and also the temperature range of the N* phase. The selective reflection measurements revealed that the pitch of the N* phase was either temperature sensitive or temperature insensitive. Temperature-dependent CD (CD) spectra were recorded for the planar texture of the N* phase formed by a dimer, as a representative case. The presence of an intense neg. CD band suggests the left-handed screw sense of the N* phase helix.
4224-70-8, 6-bromohexanoic acid is an organobromine compound comprising hexanoic acid having a bromo substituent at the 6-position. It derives from a hexanoic acid.
6-Bromohexanoic acid is a useful research compound. Its molecular formula is C6H11BrO2 and its molecular weight is 195.05 g/mol. The purity is usually 95%.
6-Bromohexanoic acid is useful for the preparation of anti-CTLA4 compounds as antitumor agents.
6-Bromohexanoic acid is a fatty acid that has been shown to be an effective agent for the treatment of cancer. It is used in gene therapy to inhibit the growth of cancer cells by binding to and then activating transcription factors. 6-Bromohexanoic acid can also be used as a chemotherapeutic agent and has been shown to cause apoptosis in monoclonal antibody-treated cells. 6-Bromohexanoic acid has pharmacokinetic properties that are similar to those of other fatty acids. The reaction solution was found to have high chemical stability, which may be due to the presence of nitrogen atoms. This reaction solution was found to adsorb onto the surface of monoclonal antibodies and cell culture, altering their properties., Safety of 6-Bromohexanoic acid
