2. Khaws lub thawv ntim kom nruj rau hauv qhov chaw tsis zoo (xws li nitrogen) kom tiv thaiv hydrolysis los ntawm ya raws hauv huab cua, N-(Trimethylsilyl) imidazole CAS 18156-74-6 yuav txo cov khoom purity thiab ua tau zoo; tsuas yog siv cov khoom qhuav, tsis muaj dej thaum tuav.
3. Ua haujlwm hauv lub fume hood nrog lub qhov cua kom zoo, hnav cov tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tsho tiv no; zam kev sib cuag nrog daim tawv nqaij, qhov muag, thiab cov mucous daim nyias nyias, thiab xyuas kom meej tias qhov chaw ua haujlwm tsis muaj dej.
Cov ntaub ntawv kev nyab xeeb
1. Ua rau tawv nqaij thiab qhov muag khaus heev; Kev sib cuag nrog daim tawv nqaij tuaj yeem ua rau liab, kub hnyiab, thiab hlwv, thaum qhov muag pom tuaj yeem ua rau mob hnyav, mob, thiab muaj peev xwm puas tsuaj yog tias tsis kho sai.
2. Ua phem N-(Trimethylsilyl)imidazole CAS 18156-74-6 yog nqus tau los yog nqos; Kev nqus pa los yog huab cua tuaj yeem ua rau ua pa ua pa, kiv taub hau, thiab xeev siab, thiab kev noj zaub mov tuaj yeem ua rau mob plab, ntuav, thiab mob plab.
3. Nyob rau hauv rooj plaub ntawm kev sib cuag ntawm daim tawv nqaij, tshem tawm cov khaub ncaws tsis huv tam sim ntawd thiab yaug qhov chaw uas muaj kev cuam tshuam nrog dej txaus kom tsawg li 15 feeb; Nyob rau hauv cov ntaub ntawv ntawm qhov muag, yaug ceev faj nrog dej rau ob peb feeb, tshem tawm cov lo ntsiab muag yog hais tias tsim nyog, thiab txuas ntxiv yaug ua ntej mus nrhiav kev kho mob.
Cov txiaj ntsig ntawm Kev Siv
1. Exhibits N-(Trimethylsilyl)imidazole CAS 18156-74-6 siab silylation efficiency thiab selectivity, reacting sai nrog hydroxyl, carboxyl, thiab amino pawg nyob rau hauv me me tej yam kev mob (chav kub los yog tsis kub) tsis muaj kev cuam tshuam rau lwm pab pawg neeg.
2. Cov pab pawg tiv thaiv trimethylsilyl (TMS) qhia los ntawm TMSI yog tshem tau yooj yim nyob rau hauv me ntsis acidic tej yam kev mob (xws li, dilute hydrochloric acid, acetic acid), tso cai rau kom yooj yim deprotection tom qab cov tshuaj tiv thaiv xav tau.
3. Soluble nyob rau hauv feem ntau cov kuab tshuaj organic (xws li, dichloromethane, tetrahydrofuran, toluene), sib haum nrog ntau yam organic tshuaj tiv thaiv kab mob, thiab tsis tsim ib qho tseem ceeb los ntawm - khoom, kom huv si thiab zoo synthesis.
