Anwendungen
Beschreibung2-iodobenzoic acid and its derivatives are important pharmaceutical and chemical raw materials, which are necessary for the synthesis of various high-iodine reagents. It is commonly used as a precursor for the synthesis of 2-Iodoxybenzoic acid (IBX) and Dess-Martin peridinane, which are used as mild oxidants. It is also used in Suziki reaction.
VerwendenReagent for detection of sulfhydryl groups in proteins. 2-Iodobenzoic acid acts as a precursor in the preparation of 2-Iodoxybenzoic acid (IBX) and Dess-Martin periodinane, which finds application as an oxidizing agent in synthetic chemistry. It is also used in Suzuki reaction.
Darstellung
synthetische2-Iodobenzoic acid is obtained from Anthranilic acid by diazotization and substitution. Diazotization of Anthranilic acid with sodium nitrite in the presence of sulfuric acid, control the temperature below 10℃, filter the diazotization solution, add the mixture of potassium iodide and sulfuric acid, stir for 10min after addition, and boil. Filter, wash with sodium thiosulfate solution, 2-Iodobenzoic acid can be recrystallized from water.
