2. Trimethylphenylammonium chloride CAS 138-24-9 yog siv rau hauv kev tsim cov ion txauv resins rau dej purification thiab tshuaj sib cais txheej txheem.
3. Trimethylphenylammonium chloride yog kawm nyob rau hauv kev tshawb fawb lom neeg raws li quaternary ammonium compound kom nkag siab txog cov membrane permeability thiab cellular kev sib cuam tshuam.
Cia thiab ceev faj
1. Khaws Trimethylphenylammonium chloride nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv chav tsev kub (RT) nyob rau hauv nitrogen gas, tiv thaiv los ntawm noo noo.
2. Khaws Trimethylphenylammonium chloride CAS 138-24-9 nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm kom tsis txhob muaj kev puas tsuaj.
3. Tuav Trimethylphenylammonium chloride siv cov cuab yeej tiv thaiv tus kheej tsim nyog nrog rau cov hnab looj tes, tsom iav kev nyab xeeb, thiab nyob rau hauv lub hood fume kom tsis txhob muaj plua plav tsim thiab tiv thaiv daim tawv nqaij thiab qhov muag.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav thiab hnav cov cuab yeej tiv thaiv tag nrho nrog rau lub tshuab ua pa tsim nyog thaum tuav Trimethylphenylammonium chloride .
2. cheb cov khoom Trimethylphenylammonium chloride CAS 138-24-9 rau hauv cov thawv ntim khoom kaw, tsis muaj cov plua plav pov tseg.
3. Tiv thaiv kom tsis txhob nchuav Trimethylphenylammonium chloride los ntawm kev nkag mus rau hauv cov dej ntws los yog hauv dej, vim Trimethylphenylammonium chloride yog tshuaj lom thiab yuav tsum tsis txhob tso rau hauv ib puag ncig.
Cov ntaub ntawv kev nyab xeeb
1. Trimethylphenylammonium chloride yog tshuaj lom yog nqos (LD50 qhov ncauj nas: 121 mg / kg) thiab tshuaj lom nyob rau hauv kev sib cuag nrog daim tawv nqaij (LD50 dermal luav: 309 mg / kg), nrog GHS teeb liab lo lus "Danger".
2. Trimethylphenylammonium chloride CAS 138-24-9 ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335); combustion tsim cov pa phem xws li carbon oxides, nitrogen oxides, thiab hydrogen chloride gas.
3. Trimethylphenylammonium chloride yog cais rau kev thauj mus los raws li cov khoom muaj kuab lom (UN2811, Hazard Class 6.1, Packing Group III) thiab muaj qhov melting point ntawm 246-248 degree.
