Methyl 5-bromo-2-chlorobenzoate（CAS# 251085-87-7)

Hoʻolauna

ʻO ka methyl 5-bromo-2-chlorobenzoate he mea hoʻohuihui. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

ʻAno:

-ke kimeka: C8H6BrClO2

-Molecular kaumaha: 241.49g/mol

-Nani: ʻAʻole waihoʻoluʻu a i melemele iki

-Ka helu heheʻe: 54-57 ° C

-Pila paila: 306-309 ° C

- Haʻahaʻa solubility i ka wai

E hoʻohana:

Hoʻohana mau ʻia ka methyl 5-bromo-2-chlorobenzoate ma ke ʻano he waena i ka synthesis organik a hiki ke hoʻohana ʻia e synthesize i nā pūhui hana biologically. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka no ka synthesis o nā lāʻau lapaʻau, pesticides a me nā dyes, a hiki ke hoʻohana ʻia i nā hopena hoʻololi, tandem reactions a me ka aromatization reactions i nā hopena synthesis organik.

Hanana:

Hiki ke hoʻomākaukau ʻia ka methyl 5-bromo-2-chlorobenzoate ma ka hana ʻana i ka hoʻokuʻu ʻana i ka methyl benzoate me ka bromine i mua o ka ferrous chloride. ʻO ka mua, ua hui pū ʻia ka methyl benzoate me kahi solution ferrous chloride, hoʻohui ʻia ka bromine, a hoʻoulu ʻia ka hui ʻana i ka mahana maʻamau. Ma hope o ka hopena, ua loaʻa ka methyl 5-bromo-2-chlorobenzoate i ka huahana ma muli o ka hoʻomaʻemaʻe ʻana i ke kaʻina waikawa a me ka hoʻomaʻemaʻe crystallization.

ʻIke palekana:

- ʻO ka methyl 5-bromo-2-chlorobenzoate he mea hoʻohuihui kūlohelohe a pono e mālama pono ʻia e pale aku i ka pili pololei me ka ʻili a me ka inhalation.

-E hoʻohana i nā mea pale pilikino e like me nā mīkina lima lab, nā maka aniani a me nā ʻaʻahu lab ke hana.

-I ka mālama ʻana, e mālama i loko o kahi pahu anuanu, maloʻo a hoʻopaʻa ʻia, ma kahi mamao o ke ahi a me nā mea oxidizing.

- E ʻoluʻolu e hahai i ke ʻano o ka mālama ʻana i nā ʻōpala kemika kūloko i ka wā e hoʻolei aku ai e pale i ka haumia i ke kaiapuni.

-I ka hoʻohana ʻana a i ʻole ka lawelawe ʻana i ka pūhui, e ʻoluʻolu e nānā i nā palapala palekana kūpono a me nā ʻōlelo aʻoaʻo hana, a e hahai i nā kaʻina hana palekana lab pono.
