I-sodium chloride

I-sodium chloride

Inombolo ye-CAS: 7647-14-5

Isibizo: ityuwa yetafile; ityuwa yelitye

Iziteketiso zesiNgesi: Ityuwa eqhelekileyo; Ityuwa yetafile; Ityuwa yeRoch; Ityuwa yolwandle

Ifomula yemolekyuli: NaCl

Ubunzima bemolekyuli: 58.44

Iipropati: Ikristale emhlophe, inyibilika emanzini. Kwi-25 ° C, i-1g iyanyibilika kumanzi ayi-2.8ml, i-2.6ml yamanzi abilayo, kunye ne-10ml glycerin, kwaye iphantse inganyibiliki kwi-ethanol. Ukunyibilika kwayo emanzini kuncitshiswe kubukho be-hydrochloric acid, kwaye phantse ayinyibiliki kwi-concentrated hydrochloric acid. Isisombululo samanzi singathathi hlangothi, kunye ne-pH ye-5.0 ~ 8.0. Ukuxinana okuzalanayo 2.17. Indawo yokunyibilika 804℃. Indawo yokubilisa 1413℃. Idosi ebulalayo ephakathi (impuku, ngomlomo) yi-3.75±0.43g/kg.

Ugcino: itywiniwe kwaye igcinwe.

sebenzisa

1. I-reagent yokuhlalutya, esetyenziselwa uvavanyo lwesitshizi setyuwa ukufumanisa ukuxhathisa kwintsimbi. Umgangatho wokulinganisa i-nitrate yesilivere. I-Microdetermination ye-fluorine kunye ne-silicates. Uvavanyo lwegazi lwesiqhelo; iimvavanyo zokusebenza kwesibindi, njl.

2. I-sodium chloride yimathiriyeli ebalulekileyo esisiseko yeekhemikhali, esetyenziswa ngokubanzi kwiinkalo ezininzi ezifana namayeza, amalaphu, ukuprinta kunye nokudaya, irabha, ukutya kunye nezolimo.

3. Isetyenziselwa ukulungisa i-tris buffer, iphosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation washing buffer, LB (Luria-Bertani) medium and dialysis buffer

4. Isetyenziswa ngokubanzi kumalungiselelo amayeza kwaye isetyenziswa njenge-penetrant kwiifom zedosi ye-liquid, i-filler okanye i-agent yokugqoka kwiifom zedosi eqinile kunye neefom ze-dosage ye-semi-solid, i-diluent kwi-salting out pharmaceuticals and capsules, i-organic reaction catalyst, kunye nemathiriyeli ekrwada yamayeza.

5. Kwiinkqubo zebhayoloji, i-sodium chloride yi-electrolyte eyisiseko ekwazi ukulungelelanisa uxinzelelo lwe-osmotic, ibhalansi ye-pH kunye ne-conductivity. Idlala indima ephambili ekugcineni isakhiwo seprotheni kunye nokukhuthaza umsebenzi we-enzyme. Kubalulekile ukuzinzisa ukulungelelaniswa kweprotheyini kunye nokuvuselela ukusabela kwe-biochemical. kubalulekile.
