Kupu Whakataki
Ko te 2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-(2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-) he pūhui waro. He tātai rāpoi o C6H3BrF3NO me te taumaha rāpoi 218.99g/mol. Ko nga korero e whai ake nei mo tona ahuatanga, te whakamahinga, te hanga me nga korero haumaru:
Taiao:
-Te ahua: 2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-he mea totoka, he ma ki te marama kowhai kiripiri.
-Ira whakarewa: Ko te 90-93°C tona ira whakarewa.
-Ko te whakarewatanga: 2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-he wairewa i roto i nga whakarewa waro noa, penei i te waihano, te etera me te chloroform.
Whakamahia:
-Te rangahau matū: 2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-ka taea te whakamahi hei reagent, hei takawaenga ranei i roto i te whakahiato waro. He maha nga wa ka whakamahia hei hanga i te anga o nga ngota ngota waro uaua i roto i nga tauhohenga whakarewa-whakakore.
-Whakawhanaketanga raau taero: Na tona hanganga motuhake me nga taonga matū, ka whai waahi nui pea ki te whanaketanga o te tarukino, penei i nga mate pukupuku mate pukupuku, nga rongoa antiviral, etc.
Tikanga Whakaritenga:
2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-ka taea te synthesized e nga momo tikanga, e whai ake nei tetahi o nga tikanga whakahiato noa:
Ka tauhohehia te 2-hydroxyl pyridine ki te konupora bromide hei whakaputa i te 2-hydroxyl -3-bromopyridine. Ka tauhohehia te 3-bromopyridine ki te fluoromethyllithium ki te hoatu 2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-. I te nuinga o te wa ka mahia te whakahiatotanga i roto i te whakarewa pararopi, penei i te dimethyl sulfoxide, me te iti o te mahana.
Mōhiohio Haumaru: Te haumaru o
- 2(1H)-Pyridinone,3-bromo-5-(trifluoromethyl)-kare ano kia ata tirohia, no reira me tupato ki te whakahaere me te penapena. Ka tohutohuhia nga kaiwhakamahi ki te mau taputapu whakamarumaru whaiaro e tika ana, penei i nga karapu taiwhanga me te whakamarumaru kanohi. A ape i te tango i tana puehu, i te pa ranei ki te kiri.
-Na ona ahuatanga matū, ka paitini pea ki te taiao wai. Me whai koa ki nga tikanga haumaru e tika ana i te wa e whakamahi ana, kia kore ai e rere ki roto i te tinana wai.
-I te wa e whakamahi ana i tenei puhui, e taunaki ana kia mahi i raro i nga tikanga taiwhanga pai-hau kia kore ai e ngotea ana mea wariu. Mena ka pakaru ohorere, ka ngotea ranei, me rapu wawe ki te rongoa.
