| 2,2'-Dithiosalicylic acid Siv Thiab Synthesis |
| Chemical Properties | xim av hmoov |
| Siv | 2,2'-Dithiosalicylic acid yog ib qho organosulfur compound uas ua los ntawm dibenzothiophene metabolites uas yog nyob rau hauv lem biodegraded mus rau cov metabolites ib ntus xws li benzoic acid.Nws yog siv nyob rau hauv kev npaj ntawm ib tug tshiab chav kawm ntawv ntawm anti-HIV-1 cov neeg ua hauj. |
| Siv | 2,2′-Dithiodibenzoic acid yuav siv tau rau kev npaj cov tshiab anionic heptadecanuclear nyiaj (I) pawg, los ntawm cov tshuaj tiv thaiv nrog sib npaug molar nyiaj oxide nyob rau hauv ultrasonic tej yam kev mob ntawm 50 degree. Nws tuaj yeem siv rau kev npaj ntawm polyamides uas muaj cov nyiaj disulfide hauv lawv cov saw tseem ceeb. |
| Kev piav qhia dav dav | 2,2′-Dithiodibenzoic acid yog ib qho sulfhydryl modifying reagent. 2,2′-Dithiodibenzoic acid ntawm cocrystallization nrog imidazole los yog 4-methylimidazole affords bis (imidazolium) 2,2′-dithiodibenzoate thiab 4-methylimidazolium 2-[({12}}carboxyphenyl) disulfanyl] benzoate organic ntsev, feem. Nws kuj tseem cocrystalizes nrog isonicotinohydrazide los ntawm cov tshuaj methanol kom them taus 1: 2 cocrystal, 2,2'-dithiodibenzoic acid-isonicotinohydrazide. |
| Kev ruaj ntseg Profile | Tshuaj lom los ntawm intraperitoneal txoj kev.Thaum rhuab mus rau decomposition nws emits lom vapors ntawm SOx. |
| Synthesis | Ib txoj kev npaj ntawm 2,2'-dithiosalicylic acid yog raws li nram no: siv anthranilic acid ua raw khoom thiab ua ib tug diazotization cov tshuaj tiv thaiv nrog sodium nitrite thiab hydrochloric acid ntawm 0 rau 10 degree kom tau ib tug diazo ua kua. Cov kua reacts nrog kua sulfur dioxide rau 0.5 mus rau 3 teev nyob rau hauv lub xub ntiag ntawm ib tug catalyst thiab ib tug cocatalyst ntawm -20~~-10 degree thiab ces khaws cia ntawm 80 ~ 100 degree. rau 0.5 ~ 2 teev, txias, thiab lim kom tau 2,2'-Dithiosalicylic acid. |
