Application
1,2,4-triazole and its derivatives are important structural moieties of many pharmaceutical drugs. Triazoles can also act as ligands to form coordination complexes with transition metal ions. Due to their electron-deficient nature, they exhibit excellent electron-transport and hole-blocking properties, making them promising organic materials in material science applications.

This study evaluated the adsorption capacity of ethylenthiourea (ETU) and 1H-1,2,4-triazole (1,2,4-T) for two commercial activated carbons: charcoal-powdered activated carbon (CPAC) and bovine bone-powdered activated carbon (BPAC). The tests were conducted at a bench scale, with ETU and 1,2,4-T diluted

A series of novel 1,2,4-triazole-ciprofloxacin hybrids was designed, synthesised and evaluated in vitro against drug-susceptible and drug-resistant bacteria. A significant part of the compounds obtained showed antibacterial activity higher than the activity of ciprofloxacin, both towards Gram-positive and Gram-negative species.
