3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.

Electron impact ionization mass spectra of 1,2,4-triazine derivatives with antimicrobial activity was written by Sherif, M. H.;Abd El-Hady, H.. And the article was included in Organic Chemistry: An Indian Journal in 2013.Reference of 108940-96-1 This article mentions the following:

2-(Aminothiocarbonyl)-3-aryl-5-arylidene-1,2,4-triazin-6-ones I (R = Cl, R1 = R3 = R4 = H, R2 = Br; R = Cl, R1 = R3 = Br, R2 = MeO, R4 = H; R = R1 = R3 = R4 = H, R2 = Cl) were prepared via condensation of 4-benzylidene-5-oxazolinones with thiosemicarbazide. The corresponding 1-methyl-3-thioxo-4-aryl-6-arylidenetriazolo[2,1-a][1,2,4]triazin-7-ones II were obtained by refluxing I with Ac2O. Treatment of I with PhCOCl in AcOH yielded the corresponding 2-[(benzoylamino)thiocarbonyl]-3-aryl-5-arylidene-1,2,4-triazin-6-ones I (R4 = PhCO). The electron impact ionization mass spectra of I (R = Cl, R1 = R3 = Br, R2 = MeO, R4 = H; R = Cl, R1 = R3 = H, R2 = Br, R4 = PhCO; R = Cl, R1 = R3 = Br, R2 = MeO, R4 = PhCO) and II (R = Cl, R1 = R3 = H, R2 = Br; R = Cl, R1 = R3 = Br, R2 = MeO), showed a weak mol. ion peak and a base peak of m/z 139 resulting from a cleavage fragmentation, but I (R = Cl, R1 = R3 = R4 = H, R2 = Br) exhibited a base peak at m/z 138. Compounds I (R = R1 = R3 = H, R2 = Cl, R4 = H or PhCO) gave a characteristic fragmentation pattern with a very stable fragment at m/z 104, while II (R = R1 = R3 = H, R2 = Cl) gave m/z 119. Some of the compounds were screened for antifungal activity. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Reference of 108940-96-1).
