Nws tuaj yeem siv los ua chiral structural unit los tswj lub spatial conformation ntawm cov tshuaj molecules, txhim kho bioavailability thiab kev ua tau zoo ntawm cov tshuaj, thiab txo cov kev mob tshwm sim.
3. 4-Hydroxy-L-phenylglycine CAS 32462-30-9 yog siv rau hauv thaj chaw ntawm asymmetric synthesis raws li chiral inducer los pab cov synthesis ntawm ntau yam chiral compounds. Nyob rau tib lub sijhawm, nws tseem tuaj yeem siv los ua lub substrate rau biocatalytic cov tshuaj tiv thaiv, muab kev txhawb nqa tseem ceeb rau kev tshawb fawb tshuaj thiab kev tsim kho thiab kev tsim tshuaj zoo.

1. Khaws rau hauv qhov chaw txias, qhuav, zoo- qhov cua nkag rau hauv lub tsev khaws khoom nrog qhov ntsuas kub ntawm 0-25 degree. Tsis txhob muaj qhov kub thiab txias (oxidative deterioration yuav tshwm sim saum 30 degree) thiab qhov chaw ntub dej los tiv thaiv cov khoom los ntawm absorbing noo noo, caking thiab txo kev ua haujlwm.
2. Khaws 4-Hydroxy-L-phenylglycine CAS 32462-30-9 nyob rau hauv lub kaw lus, siv cov ntim tshwj xeeb kaw (xws li lub raj mis xim av, HDPE lub raj mis yas) kom cais cov huab cua, noo noo thiab hmoov av. Tsis txhob sib xyaw nrog cov oxidants muaj zog, muaj zog acids, muaj zog alkalis thiab lwm yam tshuaj corrosive los tiv thaiv cov tshuaj lom neeg ua rau cov khoom tsis zoo.
3. Kev ua haujlwm yuav tsum tau ua nyob rau hauv lub fume hood. Hnav cov hnab looj tes, looj tsom iav dub thiab cov tsho tiv no kom tsis txhob muaj kev sib cuag nrog cov tawv nqaij thiab cov mucous. Ntxuav tes kom huv si tom qab ua haujlwm kom tsis txhob muaj qhov khaus ntawm cov khoom seem.

1. 4-Hydroxy-L-phenylglycine CAS 32462-30-9 muaj qhov khaus me ntsis. Kev sib cuag nrog daim tawv nqaij yuav ua rau me ntsis liab, o thiab khaus, thiab kev sib cuag nrog lub qhov muag yuav ua rau stinging thiab tearing. Cov neeg rhiab heev yuav muaj kev tsis haum tshuaj me me.
2. Inhalation ntawm nws cov plua plav yog txwv tsis pub, thiab yuav tsum tau zam kev noj tsis haum. Yog tias nqus tau los yog nqus tau, tawm tam sim ntawd tawm ntawm qhov chaw, nqus cua tshiab, thiab cov neeg uas noj 4-Hydroxy-L-phenylglycine los ntawm kev ua yuam kev yuav tsum nrhiav kev kho mob raws sijhawm thiab yuav tsum tsis txhob ntuav los ntawm lawv tus kheej.
3. Thaum lub sijhawm ua haujlwm, 4-Hydroxy-L-phenylglycine CAS 32462-30-9 yog qhov tsim nyog los tswj xyuas qhov sib txawv ntawm cov hmoov av. Ntxuav lub rooj ua haujlwm hauv lub sijhawm tom qab kev sim. Cov khib nyiab pov tseg yuav tsum tau muab cais thiab pov tseg raws li kev tuav cov tshuaj lom neeg, thiab yuav tsum tsis txhob muab pov tseg ntawm qhov xav tau.

1. High optical purity (ee tus nqi ntau dua los yog sib npaug rau 99%) thiab ruaj khov chiral qauv, uas tuaj yeem ua tau raws li cov kev cai nruj ntawm cov tshuaj synthesis rau stereoconfiguration, zoo zam kev phiv los ntawm racemates, thiab txhim kho cov tshuaj zoo.
2. Solubility zoo heev, nrog zoo solubility nyob rau hauv cov polar solvents xws li dej, methanol thiab ethanol. 4-Hydroxy-L-phenylglycine CAS 32462-30-9 yog haum rau ntau yam tshuaj tiv thaiv systems, tsis muaj complex solubilization kev kho mob, simplifying lub synthesis txheej txheem.
3. Muaj zog tshuaj lom neeg ruaj khov, tsis yooj yim rau decompose nyob rau hauv cov pa tshuaj tiv thaiv tej yam kev mob (xws li me ntsis acid- puag, ib txwm kub thiab siab), tuaj yeem tiv taus ntau yam tshuaj tiv thaiv kab mob, txo qis hauv cov txheej txheem tsim khoom, thiab txhim kho cov tshuaj tiv thaiv.
