Daim ntawv thov
1. S-2-Chloromandelic acid feem ntau yog siv los ua chiral tsev thaiv thiab daws tus neeg sawv cev hauv asymmetric synthesis ntawm kws tshuaj.
2. S -2-Chloromandelic acid CAS 52950-19-3 yog ib qho tseem ceeb nruab nrab ntawm kev tsim cov tshuaj ntshiab enantiomerically, tshwj xeeb tshaj yog nyob rau hauv cov synthesis ntawm clopidogrel thiab lwm yam khoom xyaw nquag.
3. Cov tshuaj no kuj tseem siv rau hauv kev tshawb fawb los tsim cov chiral catalysts, ligands, thiab kawm txog cov tshuaj tiv thaiv stereoselective.
Cia thiab ceev faj
1. Khaws S-2-chloromandelic acid nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, tiv thaiv los ntawm lub teeb thiab noo noo.
2. Khaws lub thawv kaw kom nruj thiab sib cais ntawm cov oxidizing muaj zog thiab cov hauv paus muaj zog.
3. Kov S -2-Chloromandelic acid CAS 52950-19-3 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tsho tiv no. Tsis txhob nqus cov plua plav.
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 S -2-Chloromandelic acid CAS 52950-19-3 cov khoom spilled nrog ib tug huv, qhuav lub cuab tam thiab muab tso rau hauv ib tug haum thawv rau pov tseg.
3. Tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog ib puag ncig. Neutralize residue yog tias tsim nyog thiab ntxuav thaj chaw nrog dej thiab tshuaj ntxuav tes.
Cov ntaub ntawv kev nyab xeeb
1. S-2-Chloromandelic acid tuaj yeem ua rau muaj kev phom sij yog tias nqos, nqus tau los ntawm plua plav, lossis tiv thaiv daim tawv nqaij, thiab tuaj yeem ua rau tawv nqaij thiab qhov muag.
2. S -2-Chloromandelic acid CAS 52950-19-3 yog combustible thiab tej zaum yuav emit toxic fumes (hydrogen chloride, carbon oxides) thaum rhuab mus decomposition.
3. Nco ntsoov sab laj nrog S-2-chloromandelic acid Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm.
