Description General description 1-Methylindole-2-carboxylic acid reacts with thionyl chloride to yield sulfinyl chlorides. Application • Reactant for preparation of keto-indoles as novel indoleamine 2,3-dioxygenase (IDO) inhibitors • Reactant for synthesis of fenbufen and ethacrynic acid derivatives as potential antitumor agents via amide coupling reactions • Reactant for diastereoselective synthesis of vinylated heterocycles via ruthenium-catalyzed oxidative vinylation with alkenes • Reactant for synthesis of 2,3-dihalo indoles via hypervalent iodine mediated decarboxylative halogenation • Reactant for preparation of α-ketoamides as cathepsin S inhibitors with potential applications against tumor invasion and angiogenesis • Reactant for preparation of anthranilic acid mimics as bacterial translation inhibitors Packaging 1, 5 g in glass bottle
