Description

• General description: 2,2′-Dithiodibenzoic acid is an sulfhydryl modifying reagent.[1] 2,2′-Dithiodibenzoic acid on cocrystallization with imidazole or 4-methylimidazole affords bis(imidazolium) 2,2′-dithiodibenzoate and 4-methylimidazolium 2-[(2-carboxyphenyl)disulfanyl]benzoate organic salt, respectively.[2] It also cocrystallizes with isonicotinohydrazide from methanol solution to afford the 1:2 cocrystal, 2,2′-dithiodibenzoic acid-isonicotinohydrazide.[3]
• Application: 2,2′-Dithiodibenzoic acid may be used for the preparation of novel anionic heptadecanuclear silver(I) cluster, by the reaction with equivalent molar silver oxide under ultrasonic conditions at 50°C.[4] It may be used for the preparation of polyamides containing a disulfide bond in their main chain.[5]
