2. 2-Pyrazinecarboxylic acid CAS 98-97-5 yog ib qho tseem ceeb nruab nrab ntawm agrochemicals, ligands hauv kev sib koom ua ke chemistry, thiab cov ntaub ntawv ua haujlwm.
3. Cov compound no kuj yog siv los ua cov khoom pib rau heterocyclic synthesis thiab hauv kev tshawb fawb biochemical.

Cia thiab ceev faj

1. Khaws 2-pyrazinecarboxylic acid nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, deb ntawm tshav kub thiab incompatible ntaub ntawv xws li muaj zog oxidizing agents.
2. Khaws 2-Pyrazinecarboxylic acid CAS 98-97-5 lub thawv kaw kom nruj kom tiv thaiv kom tsis txhob ya raws thiab kev sib kis.
3. Kov nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes thiab tsom iav kev nyab xeeb, kom txo qis kev nqus plua plav thiab kev sib cuag ntawm daim tawv nqaij.

Kev kub ceev teb rau cov dej xau

1. Tshem tawm ntawm qhov chaw nchuav thiab hnav cov khoom tiv thaiv tsim nyog (cov hnab looj tes, tsom iav kev nyab xeeb, daim npog ntsej muag yog tias xav tau).
2. Sau 2-Pyrazinecarboxylic acid CAS 98-97-5 cov khoom spilled nrog cov cuab yeej huv, qhuav thiab muab tso rau hauv lub thawv tsim nyog rau kev pov tseg.
3. Tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog ib puag ncig. Ntxuav thaj chaw nrog dej thiab tshuaj ntxuav tes, ua kom nruab nrab yog tias tsim nyog.

Cov ntaub ntawv kev nyab xeeb

1. 2-Pyrazinecarboxylic acid tuaj yeem ua rau muaj kev phom sij yog tias nqos lossis nqus tau los ua hmoov av, thiab tuaj yeem ua rau tawv nqaij thiab qhov muag khaus.
2. 2-Pyrazinecarboxylic acid CAS 98-97-5 yog combustible thiab yuav emit fumes lom (nitrogen oxides, carbon oxides) thaum tshav kub kom decomposition.
3. Nco ntsoov sab laj nrog 2-pyrazinecarboxylic acid Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm.
