Chemical Properties
brown powder
Uses
2,2'-Dithiosalicylic acid is an organosulfur compound produced from dibenzothiophene metabolites that is in turn biodegraded into transient metabolites such as benzoic acid.It is used in the preparation of a new class of anti-HIV-1 agents.
Uses
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.
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.
Safety Profile
Poison by intraperitoneal route.When heated to decomposition it emits toxic vapors ofSOx.
Synthesis
A preparation method of 2,2'-dithiosalicylic acid is as follows: using anthranilic acid as raw material and performing a diazotization reaction with sodium nitrite and hydrochloric acid at 0 to 10°C to obtain a diazo liquid. The liquid reacts with liquid sulfur dioxide for 0.5 to 3 hours in the presence of a catalyst and a cocatalyst at -20~~-10°C and then is kept at 80~100°C for 0.5~2 hours, cooled, and filtered to obtain 2,2'-Dithiosalicylic acid.
