Daim ntawv thov
1. 5-Bromo-2-chlorobenzoic acid feem ntau yog siv los ua ntau yam intermediate hauv cov organic synthesis, tshwj xeeb tshaj yog rau cov tshuaj thiab agrochemicals.
2. 5-Bromo-2-Chlorobenzoic acid CAS 21739-92-4 ua lub tsev tseem ceeb rau kev npaj cov khoom xyaw tshuaj nquag (APIs) thiab lwm cov tshuaj muaj suab thaj halogenated.
3. Cov tshuaj no kuj tseem siv rau hauv kev tshawb fawb rau kev tsim cov ntaub ntawv tshiab, ligands, thiab cov khoom siv roj ntsha.
Cia thiab ceev faj
1. Khaws 5-bromo-2-chlorobenzoic acid nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, deb ntawm tshav kub, sparks, thiab qhib nplaim taws.
2. Khaws lub thawv kaw kom nruj thiab sib cais los ntawm cov muaj zog oxidizing cov neeg ua haujlwm, cov hauv paus muaj zog, thiab cov neeg ua haujlwm txo qis.
3. Kov 5-Bromo-2-Chlorobenzoic acid CAS 21739-92-4 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, thiab lub tsho tiv no. Siv lub tshuab tso pa hauv zos lossis lub fume hood kom tsis txhob nqus cov plua plav.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, ua kom qhov cua, thiab hnav cov khoom tiv thaiv uas tsim nyog ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv, thiab lub ntsej muag plua plav / lub tshuab ua pa).
2. Ua tib zoo 5-Bromo-2-Chlorobenzoic acid CAS 21739-92-4 sau cov khoom uas nchuav nrog lub cuab yeej huv si, tsis muaj teeb meem. Tsis txhob tsim cov plua plav. Muab cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom kaw, uas muaj cov ntawv pov tseg rau kev pov tseg pov tseg.
3. Tiv thaiv kom tsis txhob muaj cov khoom nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Ntxuav cov kab mob kom huv si nrog dej thiab xab npum, sau cov tshuaj ntxuav kom zoo.
Cov ntaub ntawv kev nyab xeeb
1. 5-Bromo-2-chlorobenzoic acid muaj teeb meem yog tias nqos, nqus tau plua plav, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij khaus thiab ua rau qhov muag loj.
2. 5-Bromo-2-Chlorobenzoic acid CAS 21739-92-4 yog combustible thiab tej zaum yuav emit fumes lom (hydrogen chloride, hydrogen bromide, carbon oxides) thaum rhuab mus decomposition.
3. Nco ntsoov sab laj nrog tus nom 5-bromo-2-chlorobenzoic acid Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, tshuaj lom neeg, thiab cov ntaub ntawv tswj xyuas.
