5-BROMO-2 4-DIMETHOXYPYRIMIDINE（CAS# 56686-16-9)

Hoʻolauna

ʻO ka 5-bromo-2,4-dimethoxypyrimidine ka mea hoʻohuihui kino me ke ʻano kemika C7H8BrN2O2.

ʻAno:

ʻO 5-bromo-2,4-dimethoxypyrimidine kahi paʻa keʻokeʻo keʻokeʻo me kahi ʻala ʻokoʻa. He 1.46 g/mL kona mānoanoa a he 106-108°C. Paʻa ia ma ka lumi wela, akā e decompose i ka wā e hālāwai ai me ka wela kiʻekiʻe a me ka mālamalama mālamalama.

E hoʻohana:

Hoʻohana pinepine ʻia ʻo 5-bromo-2,4-dimethoxypyrimidine ma ke ʻano he mea waena i ka synthesis organik, ʻoi aku hoʻi i ka hoʻomākaukau ʻana i nā dyes fluorescent a me nā pesticides. Hoʻohana ʻia ia e aʻo i ka pharmacology a me ka lāʻau kemika.

Kaʻina hoʻomākaukau:

Hiki ke hana ʻia ka hoʻomākaukau ʻana o 5-bromo-2,4-dimethoxypyrimidine e nā ʻano like ʻole. ʻO kahi ala maʻamau ka hana ʻana i ka 2,4-dimethoxypyrimidine me ka hydrogen bromide. Hana ʻia ka hopena i loko o kahi mea hoʻoheheʻe inert, e like me ka dimethylformamide a i ʻole dimethylphosphoramidite, me ka hoʻomehana ʻana i kahi mahana kūpono.

ʻIke palekana:

ʻO ka 5-bromo-2,4-dimethoxypyrimidine he mea hoʻonāukiuki a hoʻomāinoino, a hiki ke hana i ke kuni ma ka pili ʻana me ka ʻili a me nā maka. No laila, e hoʻokomo i nā mīkina lima a me nā maka aniani i ka wā e lawelawe ai, a pale i ka hanu ʻana i kona lepo a mahu paha. Inā pili i ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi i ka ʻōlelo aʻoaʻo olakino. Eia kekahi, pono e pale ʻia ka hoʻopili ʻana me nā mea oxidizing a me nā waikawa ikaika i ka wā o ka mālama ʻana i mea e pale ai i nā hopena ulia.
