2-(2-bromoethyl)-2H-1,2,3-triazole; CAS No.: 1260901-96-9;2-(2-bromoethyl)-2H-1,2,3-triazole. PROPERTIES: 2-(2-bromoethyl)-2H-1,2,3-triazole is a brominated triazole derivative with a molecular weight of 202.03 g/mol. This colorless liquid has a boiling point around 135-137 C at 760 mmHg. The molecule features a 1,2,3-triazole ring substituted with a 2-bromoethyl group at position 2. It demonstrates moderate solubility in common organic solvents such as acetone and ethyl acetate but limited water solubility. Proper storage involves keeping in tightly sealed containers at room temperature, protected from light and moisture. Safety considerations include the bromine substituent's potential to cause skin and respiratory irritation and the triazole ring's general toxicity. Proper protective equipment should be utilized during handling. APPLICATIONS: This compound primarily serves as a synthetic intermediate in the production of pharmaceuticals and agrochemicals, where the brominated alkyl chain provides versatile sites for nucleophilic substitution reactions. In medicinal chemistry, it has been employed in developing antifungal agents targeting Candida species and has shown utility in creating herbicides with selective activity against grassy weeds. The triazole-branched alkyl structure has also been explored in materials science for developing chiral ligands in asymmetric catalysis, leveraging the triazole's stereoelectronic effects. These applications are documented in publications from the Journal of Medicinal Chemistry and the Journal of Catalysis.
