5-BROMO-2-HYDROXY-4-METHYLPYRIDINE（CAS# 164513-38-6)

He pūhui mea ola ia me ke kumu hoʻohālike kemika C8H8BrNO. Loaʻa iā ia nā waiwai penei:1. Nani: He paʻa melemele ʻole a māmā paha.2. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka dimethyl sulfoxide.

3. Waiwai PH: He kūʻokoʻa a ʻakika liʻiliʻi paha i loko o ka wai wai.

4. Reactivity: He mea electrophilic reagent hiki ke komo i loko o ka nui organic reactions, e like me electrophilic substitution reactions, oxidation reactions, etc.

5. Paʻa: Paʻa ia i ka mahana wela, akā hiki ke decompose ma lalo o ka hana o ka wela kiʻekiʻe, oxidant a i ʻole ka waikawa ikaika.

Loaʻa iā ia ka laulā o nā noi ma ka hale hana a me ka ʻoihana, me kēia mau mea:

1. Ma keʻano he mea hoʻokalakupua kemika: hiki ke hoʻohanaʻia e like me ka electrophilic reagent, Catalyst a iʻole ka mea hoʻohaʻahaʻa i ka synthesis organik.

2. Ma keʻano he mea hoʻomalu: Ma muli o kona mau mea antibacterial, hiki ke hoʻohanaʻia no ka hoʻomākaukauʻana i nā mea mālama, hoʻohana pinepineʻia no ka paleʻana i ka lāʻau, textiles, etc.

3. Kahua lāʻau lapaʻau: hiki ke hoʻohana ʻia i ka synthesis o nā lāʻau lapaʻau a i ʻole ma ke ʻano he waena no kekahi mau lāʻau lapaʻau.

ʻO ke ʻano maʻamau o ka hoʻomākaukau ʻana i ka paʻakai ma ka hoʻopili ʻana i ka 2-picoline me ka bromine. Hiki i nā ʻanuʻu kikoʻī ke kuhikuhi i kēia ʻano hana: ʻO ka mua, ma lalo o nā kūlana hoʻololi kūpono, hoʻopili ʻia ka 2-methylpyridine me ka bromine e loaʻa ai ka 5-bromo-2-methylpyridine. A laila, ma lalo o nā kūlana alkaline, mālama ʻia ka 5-bromo -2-methyl pyridine me ka sodium hydroxide e loaʻa ai.

E pili ana i ka ʻike palekana, pono e hoʻomaopopo ʻia kēia i ka wā e hoʻohana ai a lawelawe paha i ka metala:

1. E pale i ka pili pono ana me ka ili, ka maka, ka hanu, a pela aku. E hookomo i na lako pale ponoi e like me na mīkina lima, makaaniani a me na maka.

2. E mālama i kahi ea maikaʻi i ka wā e hoʻohana ai a pale i ka hoʻohu ʻana i kona mahu.

3. Pono e waiho ʻia ka waihona i loko o kahi pahu i hoʻopaʻa ʻia, e pale i ka lā a me ka wela kiʻekiʻe.

4. Inā 'a'ai 'ole 'ia a pili 'ili paha, holoi koke me ka wai nui a 'imi i ke kauka i ka manawa.

5. I ka hoʻohana ʻana a i ʻole ka hoʻokuʻu ʻia ʻana o ka pūhui, pono e mālama i nā kānāwai kūloko a me nā hoʻoponopono a me nā kaʻina hana palekana.
