Kev Siv 2-acetylpyridine
Ua ib lub chaw tsim khoom thiab tus muag khoom loj, peb muab cov khoom noj khoom haus huv siab, Qib Khoom Noj 2-Acetylpyridine (CAS 1122-62-9), ib qho tshuaj sib xyaw ua ke tau pom zoo rau kev siv zaub mov raws li FEMA 3251. Cov khoom xyaw tseem ceeb no yog qhov tseem ceeb rau kev tsim cov txiv ntoo qab zib, zoo li pob kws thiab ua haujlwm ua cov tshuaj tseem ceeb hauv kev tsim cov tshuaj tshiab.
Cov organic compound no, tseem hu ua Methyl 2-pyridyl ketone thiab 1-(2-Pyridinyl)ethanone, yog ib yam khoom uas muaj ntxhiab tsw qab heev, muaj ntxhiab txiv ntoo nrog rau cov saj ntawm pob kws. Nws muaj nyob rau hauv ntau yam khoom noj uas tau rhaub, ua rau nws yog ib qho cuab yeej tseem ceeb rau cov neeg nyiam saj.
Cov Ntawv Thov Tseem Ceeb & Kev Siv
Cov organic compound no, tseem hu ua Methyl 2-pyridyl ketone thiab 1-(2-Pyridinyl)ethanone, yog ib yam khoom uas muaj ntxhiab tsw qab heev, muaj ntxhiab txiv ntoo nrog rau cov saj ntawm pob kws. Nws muaj nyob rau hauv ntau yam khoom noj uas tau rhaub, ua rau nws yog ib qho cuab yeej tseem ceeb rau cov neeg nyiam saj.
Cov Ntawv Thov Tseem Ceeb & Kev Siv
1. Kev Lag Luam Khoom Noj & Tsw Qab
Hauv kev lag luam tsw qab, peb cov Khoom Noj Qib 2-Acetylpyridine (FEMA 3251) yog ib qho tshuaj tsw qab muaj zog. Nws feem ntau yog siv los muab thiab txhim kho cov tsw qab, cov ntxhiab kib hauv ntau yam kev siv.
Cov Tsw Qab: Qhov tseem ceeb rau kev rov ua dua lossis txhawb nqa qhov saj ntawm cov txiv ntoo ci (txiv laum huab xeeb, txiv laum huab xeeb), pob kws, ncuav qab zib, thiab cov khoom ci.
Nqaij & Khoom Qab: Siv rau hauv cov txheej txheem tsw qab rau cov nqaij ua tiav, cov khoom noj txom ncauj qab, thiab cov kua zaub kom tsim cov cwj pwm nplua nuj, xim av, thiab ci.
2. Kev Siv Tshuaj thiab Kev Tsim Tshuaj
Tshaj li cov saj, 2-Acetylpyridine (CAS 1122-62-9) yog ib qho khoom siv tseem ceeb hauv kev tsim cov organic, tshwj xeeb tshaj yog hauv kev tshawb fawb thiab kev txhim kho tshuaj:
Tshuaj Nruab Nrab: Nws cov qauv ua haujlwm ua tus precursor rau kev tsim ntau yam heterocyclic compounds thiab cov khoom xyaw tshuaj nquag (APIs).
Qhov zoo ntawm 2-acetylpyridine
1. Muaj purity siab 99.0% min, Cov ntsiab lus siab, tsw qab ntshiab, muag khoom zoo tshaj plaws hauv tsev thiab txawv teb chaws.
2. Peb muaj daim ntawv pov thawj ISO, muaj daim ntawv pov thawj Halal thiab kosher ntawm cov khoom no.
3. Muaj peev xwm loj, thev naus laus zis siab heev, tuaj yeem ua tau raws li cov neeg siv khoom loj xaj demand.so, feem ntau muaj lub sijhawm ua haujlwm sai.
4. Peb tuaj yeem muab 10g-50g qauv dawb rau koj qhov kev kuaj mob.
Kev ntim khoom ntawm 2-acetylpyridine
