synthesized triazolium derivatives exhibit significant antibacterial and antifungalactivities in vitro. 1‐(2,4‐Difluorobenzyl)‐4‐dodecyl‐1H‐1,2,4‐triazol‐4‐ium bromide and 1‐(2,4‐Dichlorobenzyl)‐4‐dodecyl‐1H‐1,2,4‐ triazol‐4‐ium bromide were the most potent compounds against all tested strains with the MIC values ranging from 1.05 to 8.38 μM. They exhibited much stronger activities than the standard drugs
