Intshayelelo

I-organic compound kunye ne-chemical formula ye-C6H7BrN2O kunye ne-molecular weight of 197.04g / mol.

 

Iipropati zekhompawundi ziquka:

1. Imbonakalo: ayinambala ukuya kwikristale etyheli

2. indawo yokunyibilika: 110-115°C

3. indawo yokubilisa: akukho datha

 

Ingasetyenziselwa ezinye reactions in organic synthesis, ezifana coupling reactions, acyl transfer reactions of carboxylic acids, etc. Ihlala isetyenziswa njenge amayeza intermediate for synthesis ezahlukeneyo biologically esebenzayo ikhompawundi, ezifana amachiza, izitshabalalisi kunye nedayi.

 

Indlela eqhelekileyo yokulungiselela i-compound 2-bromo-5-aminopyridine iphendulwa nge-bromo methyl ether. Ukusabela kuqhutyelwa phantsi kweemeko zealkali ukuvelisa imveliso ekujoliswe kuyo.

 

Ngokubhekiselele kulwazi lokhuseleko, yi-organic compound, kwaye la manqaku alandelayo kufuneka aqatshelwe:

1. Le khompawundi inokuvelisa iigesi ezinetyhefu phantsi kweemeko ezifumileyo okanye zobushushu obuphezulu.

2. Nxiba izixhobo ezifanelekileyo zokukhusela, njengeeglavu zekhemikhali kunye neeglavu.

3. ugweme ukudibanisa nolusu, amehlo kunye nomgudu wokuphefumula, ugweme ukuphefumla umsi / uthuli / igesi / umphunga / ukutshiza.

4. kufuneka igcinwe kwindawo eyomileyo, evaliweyo, kwindawo engenamoya, kude namadangatye avulekileyo kunye nemithombo yokushisa.

 

Xa usebenzisa okanye uphethe i-compound, kufuneka ulandele imigaqo efanelekileyo yokusebenza yokhuseleko kwaye ubhekiselele kwiphepha ledatha yokhuseleko yekhompawundi. Ukuba kuyimfuneko, qhagamshelana nengcali yeekhemikhali ngolwazi oluthe kratya.
