2-Bromobenzonitrile CAS 2042-37-7

1. 2-Bromobenzonitrile feem ntau yog siv los ua ntau lub tsev thaiv hauv cov organic synthesis rau tshuaj, agrochemicals, thiab cov khoom siv. Nws reactivity yog vim lub electron -deficient aromatic system los ntawm cov pab pawg neeg nitrile, uas ua rau ob qho tib si nucleophilic aromatic hloov thiab ntoo khaub lig-coupling tshua zoo li Suzuki-Miyaura couplings.
2. Cov tshuaj ua haujlwm ua haujlwm tseem ceeb hauv cov tshuaj chemistry rau synthesizing bioactive molecules, nrog rau cov precursors rau cov tshuaj kub siab (piv txwv li, o-tolyl benzonitrile), cov tshuaj tiv thaiv kab mob, thiab muaj peev xwm tiv thaiv -Alzheimer los yog anti-Parkinzonitrile} cov neeg sawv cev{{{ 2042-37-7 kuj tseem siv los ua cov khoom pib rau cov tshiab benzothiophene derivatives nrog cov tshuaj tua kab mob thiab tshuaj tua kab mob.
3. Cov ntawv thov ntawm 2-Bromobenzonitrile kuj suav nrog nws lub luag haujlwm hauv photoredox dehalogenation cov tshuaj tiv thaiv thiab ua cov tshuaj reagent hauv cov tshuaj tiv thaiv uas xav tau cov khoom siv hluav taws xob nplua nuj rau nucleophilic hloov pauv (lossis ntxiv) cov tshuaj tiv thaiv.

1. Khaws 2-Bromobenzonitrile nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated cheeb tsam kom deb ntawm cov khoom incompatible. Pom zoo cia yog qis dua +30℃lossis ntawm qhov kub thiab txias, tiv thaiv lub teeb thiab noo noo.
2. Khaws 2-Bromobenzonitrile kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab cov hauv paus muaj zog los tiv thaiv kev puas tsuaj. Nws yog ruaj khov nyob rau hauv ib txwm cia thiab tuav tej yam kev mob.
3. Ib txwm siv 2-Bromobenzonitrile CAS 2042-37-7 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv. Zam kom tsis txhob muaj plua plav thiab ua kom muaj cua txaus los yog siv hauv lub fume hood thaum tuav 2-Bromobenzonitrile.

1. Tam sim ntawd cais qhov chaw nchuav thiab ua kom muaj cua txaus; muaj 2-Bromobenzonitrile siv inert, tsis-combustible absorbent khoom (xws li, xuab zeb) thiab tsis txhob tsim cov plua plav.
2. Ua tib zoo cheb cov spilled 2-Bromobenzonitrile siv cov cuab yeej huv si, tsis muaj teeb meem, thiab muab cov khoom khaws cia rau hauv ib lub thawv ntim tshuaj khib nyiab pov tseg, muab pov tseg kom raug raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm 2-Bromobenzonitrile CAS 2042-37-7 yuav tsum hnav PPE tsim nyog suav nrog cov cuab yeej ua pa ntawm tus kheej (SCBA) yog tias tsim nyog thaum ntxuav; tiv thaiv cov ntaub ntawv los ntawm kev nkag mus rau hauv qhov dej los yog txoj kev hauv dej. 2-Bromobenzonitrile yog cais rau kev thauj mus los (UN3439, Hazard Class 6.1, PG III).

1. 2-Bromobenzonitrile yog cais nrog GHS teeb liab lo lus "Warning". Nws muaj teeb meem yog tias nqos tau (H302), teeb meem ntawm daim tawv nqaij (H312), thiab ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab ua pa ua pa (H335). Qee qhov kev faib tawm kuj suav nrog H331 (tshuaj lom yog tias nqus tau).
2. 2-Bromobenzonitrile is combustible with a flash point >110℃(230℃F). Nws cov thermal decomposition lossis combustion tuaj yeem tsim cov pa phem thiab ua rau muaj pa phem xws li carbon oxides, nitrogen oxides, thiab hydrogen bromide. 2-Bromobenzonitrile CAS 2042-37-7 yog teeb meem rau cov dej hauv lub neej nrog cov teebmeem ntev ntev (H412) thiab muaj kev phom sij ntawm WG2 (lub teb chaws Yelemees).
3. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau 2-Bromobenzonitrile kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+}P338 rau qhov muag, P302+P352 rau daim tawv nqaij, P304+P340 rau kev nqus pa), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P261 (tsis txhob ua pa plua plav), P280 (hnav looj hnab looj tes tiv thaiv qhov muag), thiab P405 (khoom kaw cia).
