2. L-tert-Leucine CAS 20859-02-3 ua hauj lwm raws li ib tug ntau yam precursor rau synthesizing chiral catalysts thiab ligands, nrog rau (S)-tert-butylPHOX phosphinooxazolines polymers (II) ligands rau cov kev daws teeb meem Secondary alcohols, thiab tert-leucine-derived N-acetylthiazolidinethione auxiliaries rau cov tshuaj diastereoselective acetate aldol heev.
3. L-tert-Leucine yog ua hauj lwm raws li chiral pib cov khoom nyob rau hauv hlau-dawb tandem radical cyclization cov tshuaj tiv thaiv los ua ke 6-alkyl/acyl phenanthridines thiab ua ib qho catalyst rau enantioselective oxidative coupling thiab cyclization ntawm hydroxyl quinone.
4. Cov kws tshawb fawb siv L-tert-Leucine CAS 20859-02-3 hauv cov kev tshawb fawb organic chemistry, qhov uas nws tau siv ua ke nrog NaBH₄ rau asymmetric txo ntawm ketones, ua tiav txog li 95% enantiomeric tshaj nyob rau hauv lub syntheemist ntawm calcium.

1. L-tert-Leucine yuav tsum tau muab khaws cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua nyob ib puag ncig, tiv thaiv los ntawm lub teeb, nrog kev pom zoo cia ntawm chav tsev kub hauv qhov chaw tsaus, qhuav.
2. Cov khoom lag luam tsis raug cais raws li cov khoom siv phom sij raws li GHS cov qauv thiab tsis tas yuav tsum muaj cov lus qhia; Txawm li cas los xij, yuav tsum tau ua raws li cov qauv kev ceev faj. L-tert-Leucine CAS 20859-02-3 yog incompatible nrog muaj zog oxidizing agents.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (nitrile roj hmab, qhov tsawg kawg nkaus 0.11 mm thickness kuaj rau EN 374), tsom iav kev nyab xeeb nrog sab - cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv thaum tuav cov tshuaj no . Rau cov plua plav tsis zoo, hom N95 (US) lossis hom P1 (EN 143) plua plav npog yuav siv tau.
4. Tsis txhob tsim cov plua plav thiab aerosols, siv cov cuab yeej uas tsis yog- ua kom tsis muaj teeb meem, tiv thaiv electrostatic tawm, thiab ntxuav kom huv si tom qab tuav. Cov khoom muaj WGK 1 (qhov muaj peev xwm ua rau dej tsis zoo) thiab tsis tas yuav tsum tau ceev faj tshwj xeeb.

1. Tshem tawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, thiab tsis txhob muaj plua plav tawm thaum L-tert-Leucine raug tso tawm; hnav cov cuab yeej tiv thaiv tus kheej tag nrho suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub ntsej muag plua plav tsim nyog.
2. Sau L-tert-Leucine CAS 20859-02-3 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas siv cov cuab yeej tsis muaj teeb, thiab muab tso rau hauv cov thawv kaw tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa; Tsis muaj kev ceev faj ib puag ncig tshwj xeeb, txawm tias tawm mus rau hauv cov dej yuav tsum tau tiv thaiv.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig; Cov khoom no tsis raug cais raws li cov khoom txaus ntshai rau kev thauj mus los (ADR / RID / IMDG / IATA: Tsis yog cov khoom txaus ntshai) thiab muab nyiaj ntxiv rau cov tuam txhab pov tseg pov tseg.

1. L-tert-Leucine yog combustible nrog NFPA qhov ntsuas hluav taws kub ntawm 1 (cov khoom yuav tsum tau ua kom muaj cua sov ua ntej ignition). Nyob rau hauv cov xwm txheej hluav taws kub, cov khoom puas tsuaj muaj xws li cov pa roj carbon monoxide, carbon dioxide, thiab nitrogen oxides (NOx).
2. Siv L-tert-Leucine CAS 20859-02-3 cov tshuaj tsuag dej, dej cawv-resistant ua npuas ncauj, qhuav tshuaj hmoov, los yog carbon dioxide tua hluav taws uas muaj cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha vim nws yuav tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav nws tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hlawv L-tert-Leucine vim yog cov pa phem uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, txias cov thawv ntim nrog cov tshuaj tsuag dej los ntawm qhov chaw tiv thaiv, thiab muaj hluav taws los tiv thaiv ib puag ncig.
