Kotsi le Polokeho

Likhoutu tsa Kotsi R36/37/38 – Ho tena mahlo, tsamaiso ya ho hema le letlalo.
R41 – Kotsi ya tshenyo e kgolo mahlong
R37/38 – E tenang tsamaiso ya ho hema le letlalo.
R25 – E na le chefo ha e koetsoe
Tlhaloso ea Tšireletseho S26 - Ha u kopana le mahlo, hlatsoa hang-hang ka metsi a mangata 'me u batle keletso ea bongaka.
S45 – Ha ho ka etsahala kotsi kapa ha o ikutlwa o sa phele hantle, batla keletso ya bongaka hanghang (bontsha leibole neng kapa neng ha ho kgoneha.)
S39 - Apara ts'ireletso ea mahlo / sefahleho.

5-bromo-2,3-dichloropyridine ke motsoako oa organic o nang le foromo ea lik'hemik'hale C5H2BrCl2N. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo ena:

Tlhaho:
-Ponahalo: Ha e na 'mala ho isa ho kristale e mosehla e khanyang kapa phofo e khanyang
- Sebaka se qhibilihang: 62-65°C
- Sebaka se belang: 248°C
- Boima: 1.88g/cm³
-ha e qhibilihe ka metsing, e qhibilihang ka har'a li-solvents (tse kang chloroform, methanol, ether, joalo-joalo)

Sebelisa:
- 5-bromo-2,3-dichloropyridine ke karolo ea bohlokoa ea lipakeng tsa organic synthesis.
-E ka sebelisoa ho lokisa metsoako e ngotsoeng e nang le li-isotopes tsa carbon radioactive.

Mokhoa oa ho itokisa:
Mokhoa oa ho lokisetsa oa -5-bromo-2,3-dichloropyridine hangata o fumanoa ka bromination substitution itšoara joang ea 2,3-dichloro-5-nitropyridine. Mokhoa o ikhethileng ke ho qala ka ho arabela 2,3-dichloro-5-nitropyridine ka phosphorus trichloride, ebe o etsa karabelo ea phetisetso ea bromination ka bromine.

Lintlha tsa Tšireletseho:
- 5-bromo-2,3-dichloropyridine ke motsoako oa lintho tse phelang 'me o hloka ho latela mekhoa e sireletsehileng ea ho sebetsa ha o sebetsana le ho sebelisoa.
-E ka 'na ea halefisa mahlo, letlalo le tsamaiso ea ho hema, kahoo roala likhalase, li-gloves le mask.
-Ka kopo e boloke hantle, hole le mollo, mocheso le oxidant, 'me u qobe ho kopana le acid e matla le alkali.
-Ha motho a hema kapa a kopana ka phoso, hloekisa sebaka se amehileng hang-hang 'me u batle thuso ea bongaka.
