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. 1575-37-7, formula is C6H7BrN2, Name is 4-Bromobenzene-1,2-diamine, Quality Control of 1575-37-7
Sosa, Alexis A.;Palermo, Valeria;Langer, Peter;Luque, Rafael;Romanelli, Gustavo P.;Pizzio, Luis R. research published 《 Tungstophosphoric acid/mesoporous silicas as suitable catalysts in quinoxaline synthesis》, the research content is summarized as follows. Quinoxalines and their derivatives are of great value in the chem. and biol. sciences. These compounds are found in dyes, agrochems., and are used as building blocks of drugs for the treatment of different diseases. Quinoxalines and their derivatives are synthesized by a heterogeneous catalysis procedure that involves the condensation of 1,2-dicarbonyl compounds with aromatic 1,2-diamines in an aprotic organic solvent at low temperature, in the presence of an acid catalyst composed of tungstophosphoric acid immobilized on mesoporous silica nanoparticles. The reaction process is very simple and the catalyst, besides being very active and selective, can be easily isolated from the reaction medium and reused in subsequent reactions without considerable loss of activity. Quinoxalines are obtained in short reaction time with excellent yields and high purity.
Quality Control of 1575-37-7, 4-Bromo-1,2-diaminobenzene can be obtained from 1,2-diaminobenzene via acetylation followed by bromination and alkaline hydrolysis.
4-Bromobenzene-1,2-diamine, also known as 4-Bromobenzene-1,2-diamine, is a useful research compound. Its molecular formula is C6H7BrN2 and its molecular weight is 187.04 g/mol. The purity is usually 95%.
4-Bromo-1,2-diaminobenzene is a dye that is used in diagnostic
procedures to detect the presence of amide groups. 4-Bromo-1,2-diaminobenzene can be used as an inhibitor for cationic polymerization reactions. It also has tuberculostatic activity and inhibits the growth of Mycobacterium tuberculosis. This compound reacts with aniline to form a benzimidazole derivative that contains a reactive amine group. The reaction between this amine group and different electrophiles generates benzimidazole compounds with different properties that are useful in nucleophilic attack reactions. The reaction between 4-bromo-1,2-diaminobenzene and methyl ethyl sulfide produces a luminescent probe that can be used to detect hydrogen bonds., 1575-37-7.
