Cov kws tshawb fawb siv D-Tyrosine CAS 556-02-5 hauv kev tshawb fawb dermatological rau cov tawv nqaij pigmentation thiab tiv thaiv UV, hauv kev tshawb fawb khoom noj khoom haus kev ua si rau kev txhim kho kev ua tau zoo, thiab ua lub tsev thaiv hauv kev tsim tshuaj rau cov xwm txheej xws li kev nyuaj siab thiab kev ntxhov siab.
Cia thiab ceev faj
1. D-Tyrosine yuav tsum muab khaws cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua; hmoov daim ntawv yog ruaj khov mus txog 3 xyoos ntawm -20℃lossis 2 xyoos ntawm 4 degree.
2. D-Tyrosine CAS 556-02-5 yog cais nrog cov lej phom sij Xi thiab cov kab lus txaus ntshai R36/37/38 (Is khaus rau qhov muag, ua pa, thiab tawv nqaij), nrog rau cov lus txaus ntshai H315 (Ua rau tawv nqaij khaus), H319 (Ua rau qhov muag mob hnyav), thiab H35 ua rau ua pa.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb nrog sab- cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv thaum tuav D-tyrosine, zam kev tsim cov plua plav thiab aerosols, thiab ua kom muaj cua txaus hauv chaw ua haujlwm.
4. Khaws kom deb ntawm cov khoom siv tsis sib xws xws li muaj zog oxidizing tus neeg sawv cev; khaws cia ntawm RT (chav tsev kub); rau cov tshuaj cia, npaj aliquots nyob rau hauv nruj nreem kaw vials thiab siv nyob rau hauv 1 lub hlis ntawm -20 degree, tsis txhob rov qab freeze-thaw cycles .
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, ua kom muaj cua txaus, thiab hnav cov khoom tiv thaiv tus kheej tag nrho nrog rau cov tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab nqus plua plav tsim nyog thaum D-tyrosine tso tawm.
2. Sau D-Tyrosine CAS 556-02-5 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; ventilate cheeb tsam thiab ntxuav qhov chaw nchuav tom qab nqa cov khoom tiav.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig; sab laj nrog lub xeev thiab cov kev cai hauv zos rau cov txheej txheem pov tseg kom raug.
Kev tiv thaiv hluav taws
1. D-Tyrosine is not classified as highly flammable (NFPA fire rating of 0-1) but may decompose under fire conditions, with a melting point >300 degree.
2. Siv cov tshuaj tsuag dej, tshuaj qhuav hmoov, carbon dioxide, los yog cawv- ua npuas ncauj resistant los tua hluav taws nrog cov khoom; Cov neeg tua hluav taws yuav tsum hnav PPE thiab SCBA nrog lub ntsej muag puv ua haujlwm hauv hom zoo siab.
3. Kev puas tsuaj D-Tyrosine CAS 556-02-5 decomposition khoom tsim nyob rau hauv hluav taws kub muaj xws li cov pa roj carbon monoxide, carbon dioxide, thiab nitrogen oxides (NOx).
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, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig.
