Synthesis of N-alkylated derivatives of imidazole as antibacterial agents
N-Alkylation of imidazole, 2-methylimidazole and 2-methyl-4-nitroimidazole have been carried out to achieve effective antibacterial agents. The products were then investigated for antibacterial activity against Escherichia coil, Staphylococcus aureus and Pseudomonas aeruginosa. Antibacterial effects of 1-alkylimidazole derivatives increase as the number of carbons in alkyl chain increases up to nine carbons. Also substitution of 2-methyl and 2-methyl-4-nitro groups on imidazole ring increases the antibacterial activity.
Swimming pool or like aqueous system containing an imidazolium, pyrazolium or triazolium salt as sanitizer
The use of oligomeric imidazolium, pyrazolium and triazolium salts as swimming pool sanitizers having improved compatibility with chlorine. Bisimidazolium salts are preformed.
