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. 4897-84-1, formula is C5H9BrO2, Name is Methyl 4-bromobutanoate, Recommanded Product: Methyl 4-bromobutanoate
Gerth, Marieke;Berrocal, Jose Augusto;Bochicchio, Davide;Pavan, Giovanni M.;Voets, Ilja K. research published 《 Discordant Supramolecular Fibres Reversibly Depolymerised by Temperature and Light》, the research content is summarized as follows. Synthetic stimuli responsive supramol. polymers attract increasing interest for their ability to mimic the unique properties of natural assemblies. Here we focus on the well-studied benzene-1,3,5-tricarboxamide (BTA) motif, and substitute it with two (S)-3,7-dimethyloctyl groups and an azobenzene photoswitch. We demonstrate the UV (λ=365 nm) induced depolymerization of the helical hydrogen-bonded polymers in methylcyclohexane (MCH) through CD and UV-vis spectroscopy in dilute solution (15μM), and NMR and iPAINT super-resolution microscopy in concentrated solution (300μM). The superstructure can be regenerated after thermal depolymerization, while repeated depolymerization can be reversed without degradation by irradiating at λ=455 nm. Mol. dynamics simulations show that the most energetically favorable configuration for these polymers in MCH is a left-handed helical network of hydrogen-bonds between the BTA cores surrounded by two right-handed helixes of azobenzenes. The responsiveness to two orthogonal triggers across a broad concentration range holds promise for use in, for example, photo-responsive gelation.
4897-84-1, Methyl 4-bromobutyrate,also as known as 4-Bromobutyric acid methyl ester, is a useful research compound. Its molecular formula is C5H9BrO2 and its molecular weight is 181.03 g/mol. The purity is usually 95%.
4-Bromobutyric acid methyl ester is a synthetic compound that can be used to inhibit the activity of the G1 phase cyclin-dependent kinases. It has been shown to inhibit protein synthesis by alkylating the amino groups of proteins and fatty acids. 4-Bromobutyric acid methyl ester also inhibits the growth of cancer cell lines, such as renal carcinoma cells. The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion., Recommanded Product: Methyl 4-bromobutanoate
