5-Nitro-2-furoic acid Usage And Synthesis

Chemical Properties

yellow crystalline powder

Uses

5-Nitro-2-furoic acid is a representative of 2-substituted 5-nitrofurans. A number of nitrofurans have been used as antibacterial, antiprotozoal, and anthelmintic drugs in humans and animals. 2-Substituted 5-nitrofurans have been used worldwide as human and veterinary medicines, food preservatives, and feed additives, and they are utilized in human medicine as antibacterial agents. Therefore, the relationship between the antibacterial effect and the mutagenicity of these compounds and their oxidized metabolites is important. Comparison of the antibacterial effects and genotoxic potencies of nitrofuran drugs and their oxidative metabolites may provide a new direction for selecting nitrofuran drugs for human use.

Uses

5-Nitro-2-furoic acid was used in the preparation of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazines and [1,2,4]triazolo[3,4-b][1,3,4] thiadiazoles. The FT-IR and FT-Raman spectra of 5-Nitro-2-furoic acid has also been studied.
