Daim ntawv thov
1. Ua raws li qhov nruab nrab tseem ceeb rau kev sib txuas cov tshuaj sib txuas rau cov kab mob neurological thiab cov hlab plawv.
2. Ua haujlwm rau 3 5-Dibromopyridine CAS 64248-63-1 ua lub tsev tseem ceeb rau kev tsim tshuaj agrochemicals xws li tshuaj tua kab thiab tshuaj tua kab.
3. Ua haujlwm raws li cov tshuaj reagent rau kev npaj hloov pauv pyridine derivatives hauv cov organic synthesis zoo.
Cia thiab ceev faj
1. Khaws rau hauv cov thawv ntim amber kaw ntawm 10-25℃hauv qhov txias, qhuav, zoo- qhov cua qhov chaw kom deb ntawm tshav kub thiab muaj zog oxidants.
2. Hnav 3 5-Dibromopyridine CAS 64248-63-1 nitrile hnab looj tes, looj tsom iav dub thiab lub ntsej muag plua plav kom tsis txhob nqus cov hmoov, tiv thaiv daim tawv nqaij thiab kev noj tsis zoo.
3. Tiv thaiv kom tsis txhob ya raws thiab hla - paug; pov tseg cov pov tseg tsuas yog los ntawm kev tso cai muaj tshuaj lom neeg ua haujlwm.
Dab tsi yog qhov txiaj ntsig ntawm kev noj 3 5-Dibromopyridine?
1. Nqa symmetric bromine substituents uas ua kom muaj txiaj ntsig cross-coupling kev cuam tshuam hauv cov organic synthesis.
2. Muab 3 5-Dibromopyridine CAS 64248-63-1 ib tug ruaj khov pyridine nplhaib qauv uas txhim khu lub bioactivity thiab selectivity ntawm derived khoom.
3. Muab pov thawj zoo solubility nyob rau hauv cov organic solvents, kom ntseeg tau homogeneous cov tshuaj tiv thaiv systems thiab zoo ib yam yields.
