Daim ntawv thov
1. Alpha-Toluenesulfonyl chloride yog ib qho tseem ceeb ntawm cov organic intermediate rau synthesizing sulfa tshuaj (xws li, antitumor agent E707), enzyme inhibitors, thiab immunomodulators .
2. Alpha-Toluenesulfonyl chloride CAS 1939-99-7 ua haujlwm ua reagent rau kev tiv thaiv cov amino pawg xws li benzylsulfonamides, uas tuaj yeem cleaved reductively (Na/NH₃) los yog ntawm photolysis; nws kuj tiv thaiv pawg cawv li benzylsulfonates.
3. Kev siv ntawm Alpha-Toluenesulfonyl chloride txuas ntxiv mus ua ib qho khoom siv hluav taws xob hauv palladium-cov tshuaj tiv thaiv catalyzed (xws li, reductive aminocarbonylation ntawm nitroarenes) thiab siv rau hauv cov tshuaj ntxuav, dyes, thiab tshuaj tua kab mob.
Cia thiab ceev faj
1. Khaws Alpha-Toluenesulfonyl chloride nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv inert gas (argon) nyob rau hauv ib qho chaw txias, qhuav; Cov lus pom zoo ntawm qhov kub thiab txias sib txawv (2-8 degree, qis dua +30 degree, lossis -20℃hauv qab argon).
2. Khaws Alpha-Toluenesulfonyl chloride nruj me ntsis kom deb ntawm cov dej noo thiab dej, vim nws decomposes sai, tso cov pa phem thiab corrosive gases.
3. Ib txwm Alpha-Toluenesulfonyl chloride CAS 1939-99-7 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj thiab tiv thaiv qhov muag / ntsej muag; kov tsuas yog nyob rau hauv cov chaw nruab rau corrosive solids (UN3096/3261, Class 8, PG II).
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav; tsis tsim plua plav. Muaj Alpha-Toluenesulfonyl chloride siv qhuav, inert, tsis yog- cov khoom siv hluav taws xob nqus tau thiab tsis txhob sib cuag nrog dej.
2. Ua tib zoo sau Alpha-Toluenesulfonyl chloride CAS 1939-99-7 mus rau hauv lub thawv ntim tshuaj tiv thaiv corrosion-resistant rau pov tseg; Ua raws li cov cai rau corrosive khoom, acidic, organic, nos (UN3261).
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg puv - cov khoom tiv thaiv; Tom qab tshem tawm cov khaub ncaws tsis huv, yaug daim tawv nqaij nrog dej / da dej tam sim ntawd.
Cov ntaub ntawv kev nyab xeeb
1. Alpha-Toluenesulfonyl chloride yog corrosive (GHS05, Danger) ua rau tawv nqaij kub hnyiab thiab mob qhov muag loj (H314, H318); Kev nqus pa tuaj yeem ua rau muaj kev raug mob corrosive rau lub ntsws thiab lub ntsws.
2. Alpha-Toluenesulfonyl chloride reacts nrog dej thaum sib cuag, decomposes, thiab yuav tsum tau nruj tiv thaiv ya raws; thermal decomposition ua rau cov pa phem thiab corrosive xws li sulfur oxides thiab hydrogen chloride.
3. Ib txwm Alpha-Toluenesulfonyl chloride CAS 1939-99-7 sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Alpha-Toluenesulfonyl chloride kom tiav kev phom sij, kev pab thawj zaug, thiab cov ntaub ntawv tuav; Cov lus ceeb toom muaj xws li P260, P280, P303+P361+P353, P305+P351+P338, thiab P301+P330+P331 .
