Synthesis and study on the spectral properties of novel compounds containing bromo-arylbenzothiazole moiety was written by Hu, Ji;Li, Zai-jun;Song, Qi-jun. And the article was included in Huaxue Shiji in 2008.Reference of 108940-96-1 This article mentions the following:
In the present paper, pthalylimide as the raw material orderly reacted was subjected to nitration, reduction, mercaptization, and hydrazination reactions, resp., for the synthesis 6-amino-7-mercapto-2,3-dihydro-1,4-phthalazinedione (AMHP). AMHP reacted with 4-bromobenzaldehyde, 3,5-dibromo-4-hydroxybenzaldehyde, 3, 5-dibromo-2-hydroxybenzaldehyde, 3, 5-dibromo-4-methoxy-benzaldehyde and tribromobenzaldehyde to form different compounds containing 2-arybenzothiazole moiety, which were abbreviated as p-Br-AMHP, DB-p-H-AMHP, DB-o-H-AMHP, DB-p-MO-AMHP and TB-AMHP, resp., and their structures were characterized by IR, NMR and elemental anal. Then the spectral properties of new compounds were investigated investigated in detail, and the results exhibited that they were all good luminescent reagents and their chemiluminescence intensities were obviously better than that of conventional illuminant luminol. Among these compounds, DB-p-H-AMHP was the best and its chemiluminescence intensity was 230 times that of luminol, indicating that the reagent can be widely applied in anal. chem. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Reference of 108940-96-1).
3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Reference of 108940-96-1
