5-Bromo-3-chloro-2-pyridinecarboxylic acid methyl ester (CAS # 1214336-41-0)

ʻO ka Methyl 5-bromo-3-chloro-2-pyridine carboxylate kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:
ʻO ka Methyl 5-bromo-3-chloro-2-pyridine carboxylate he wai kala ʻole a melemele paha. Paʻa paʻa ia ma ka lumi wela, akā hiki ke decomposition i ka wā i ʻike ʻia i nā wela kiʻekiʻe, māmā, a i ʻole nā ​​​​mea ʻona ikaika.

E hoʻohana:
Loaʻa i ka Methyl 5-bromo-3-chloro-2-pyridine carboxylic acid kekahi waiwai hoʻohana ma ke kahua kemika. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui i nā reagents synthesis organik a me nā catalysts.

Hanana:
Hiki ke hoʻokō ʻia ke ʻano hoʻomākaukau o ka methyl 5-bromo-3-chloro-2-pyridine carboxylic acid ma o ka bromination a me ka chlorination o ka methyl 2-pyrolinate ester. Ma lalo o nā kūlana kūpono, hoʻopili ʻia ka methyl 2-picolinate me ka bromine a me ka chlorine e loaʻa ai ka huahana i koho ʻia.

ʻIke palekana: He mea hoʻouluulu e hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōnaehana hanu. E hōʻalo i ka hanu ʻana i nā kinoea, nā mahu, ka noe, a i ʻole ka lepo, a pale i ka pulu ʻana i ka ʻili i ka wā e pili ana. Pono e ʻaʻahu ʻia nā lako pale pilikino (PPE), me nā makaaniani palekana, nā mīkina lima pale a me nā ʻaʻahu i ka wā e lawelawe ai. Inā pono, e hana i loko o kahi ea maikaʻi a hahai i nā kaʻina hana palekana kūpono. Pono e hoʻomaʻemaʻe maikaʻi ʻia ma hope o ka mālama ʻana e pale aku i ka haumia i ke kaiapuni.
