ʻO 8-bromo-1, 6-naphythyridin-5 (6h)-one he mea hoʻohuihui me ke ʻano mole mole C13H8BrNO, he mea paʻa paʻa.

ʻO nā waiwai o kēia hui:

1. Nānā: 8-bromo-1, 6-naphythyridin-5 (6h) -he keʻokeʻo a i ʻole ka pauka aniani melemele māmā.
2. Ka helu heheʻe: loaʻa kahi helu heheʻe kiʻekiʻe, ma kahi o 206-210 ℃.
3. Solubility: Loaʻa ka solubility maikaʻi i kekahi mau mea hoʻoheheʻe organik (e like me chloroform, acetone a me dimethyl sulfoxide).

Loaʻa iā ia nā noi he nui i ka hale hana a me ka ʻoihana:

1. Chemical reagents: hiki ke hoʻohana ʻia e like me nā reagents i nā hopena synthesis organik, e like me nā noi i ka synthesis o nā lāʻau lapaʻau a me nā pesticides.
2. Mea kiʻi kiʻi kiʻi: ma muli o ke ʻano kūikawā o kona ʻano mole, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea photosensitive.
3. Organic synthesis intermediates: hiki ke hoʻohana ʻia e like me nā intermediates no ka synthesis o nā pūhui ʻē aʻe.

E pili ana i ke ʻano o ka hoʻomākaukau ʻana, hiki ke hoʻomākaukau ʻia ka 8-bromo-1,6-naphthyridin-5(6h)-one ma nā ʻanuʻu aʻe:

1. ʻO ka mua, hoʻopili ʻia ka 1,6-naphthoketone me ka hydrogen bromide. Hiki ke hoʻokō ʻia nā ʻano hopena ma ka hoʻomehana ʻana i mua o ka acetic acid.
2. ʻO ka huahana hopena he 8-bromo -1,6-naphthoketone, hana hou aku:
a. Hoʻopili ʻia ka 8-bromo -1,6-naphthoketone me ka pyridine ma lalo o ka acid catalysis.
B. ʻO nā kūlana hoʻololi he hopena Reflux, maʻamau i ka acetic acid.
c. ʻO ka huahana i loaʻa ma ka hopena ʻo 8-bromo-1,6-naphthyridin-5(6h)-one.

E pili ana i ka ʻike palekana, 8-bromo-1,6-naphthyridin-5(6h)-one kahi hui kūlohelohe, no laila pono e lawe ʻia nā hana palekana kūpono:

1. E pale i ka pili ana me ka ili a me na maka, e like me ka pili, pono e holoi koke me ka wai nui.
2. Pono e hoʻohana ʻia ma kahi e hoʻoheheʻe maikaʻi ʻia e pale i ka hanu ʻana i kona lepo.
3. Pono e mālama ʻia mai ke ahi a me ka oxidant.
4. E hahai i nā kaʻina hana hoʻokolohua kūpono a me nā hana pale pilikino.
