Daim ntawv thov
1. 5,6-Dihydroxyindoline yog ib qho catecholamine derivative feem ntau siv los ua ib qho tseem ceeb nruab nrab ntawm kev sib txuas ntawm melanin pigments thiab ua tus thawj coj hauv kev tshawb fawb ntawm melanogenesis .
2. 5 6-Dihydroxyindoline CAS 29539-03-5 yog ib qho tseem ceeb substrate rau tyrosinase thiab lwm yam enzymes koom nyob rau hauv lub melanin biosynthesis txoj kev, ua rau nws muaj txiaj ntsig rau kev tshawb fawb ntawm pigmentation teeb meem.
3. 5,6-Dihydroxyindoline yog ua hauj lwm hauv kev tsim cov tshuaj tiv thaiv kab mob thiab cov tshuaj tua kab mob antioxidant vim nws muaj peev xwm tshem tawm cov dawb radicals thiab nqus UV hluav taws xob.
4. Nyob rau hauv tshuaj chemistry, 5,6-dihydroxyindoline yog siv nyob rau hauv lub synthesis ntawm tej zaum cov kws kho mob rau cov kab mob neurodegenerative, qhov uas nws cov qauv catechol ua raws li cov dopamine thiab lwm yam neurotransmitters.
Cia thiab ceev faj
1. 5,6-Dihydroxyindoline yuav tsum tau muab cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw tsis zoo (nitrogen lossis argon) hauv qhov chaw txias, qhuav, thiab qhov cua zoo, tiv thaiv lub teeb thiab noo noo.
2. 5 6-Dihydroxyindoline CAS 29539-03-5 yog oxygen-sensitive thiab tej zaum yuav raug oxidation sai sai thaum raug huab cua; pom zoo cia ntawm -20℃rau kev ruaj ntseg mus ntev, nrog cov kev daws teeb meem tshiab thiab siv tam sim ntawd.
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 cov tshuaj no, vim nws ua rau tawv nqaij thiab qhov muag khaus loj (H315, H319).
4. Khaws kom deb ntawm cov khoom siv tsis sib xws xws li cov tshuaj muaj zog oxidizing, muaj zog acids, thiab cov hauv paus muaj zog los tiv thaiv decomposition; zam kev tso tawm rau ib puag ncig.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, thiab hnav cov khoom tiv thaiv tus kheej nrog rau cov tshuaj lom neeg - cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab ua pa uas tsim nyog thaum 5,6-Dihydroxyindoline raug tso tawm.
2. Sau 5 6-Dihydroxyindoline CAS 29539-03-5 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas siv cov cuab yeej tsis muaj hluav taws xob, 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; decontaminate qhov chaw thiab cov khoom siv los ntawm kev txhuam nrog cawv, thiab tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov chav dej.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv ib puag ncig kev tswj hwm los ntawm kev tso cai los ntawm kev puas tsuaj los yog kev tswj hwm incineration.
Kev tiv thaiv hluav taws
1. 5,6-Dihydroxyindoline tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem decompose nyob rau hauv hluav taws kub, emitting fumes lom xws li carbon monoxide, carbon dioxide, thiab nitrogen oxides (NOx).
2. Siv 5 6-Dihydroxyindoline CAS 29539-03-5 tshuaj tsuag dej, tshuaj qhuav hmoov, carbon dioxide, los yog dej cawv-resistant npuas los tua hluav taws uas muaj cov khoom.
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 hluav taws kub 5,6-Dihydroxyindoline 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; muaj hluav taws kub los tiv thaiv ib puag ncig.
