General description

2,2′-Dithiodibenzoic acid is an sulfhydryl modifying reagent. 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. It also cocrystallizes with isonicotinohydrazide from methanol solution to afford the 1:2 cocrystal, 2,2′-dithiodibenzoic acid-isonicotinohydrazide.


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. It may be used for the preparation of polyamides containing a disulfide bond in their main chain.
