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.
D 2790 (OTTO) 2,2'-Dithiosalicylic acid, 96% Cas 119-80-2 - 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.
