ethyl 5-methoxy-1-benzofuran-2-carboxylate（CAS# 50551-56-9)

Kupu Whakataki

He pūhui waro a Ethyl. Ko nga korero e whai ake nei mo tona ahuatanga, te whakamahinga, te whakarite me nga korero haumaru:

Taiao:

-Te ahua: te wai kore tae

-Tatai rāpoi: C13H12O4

-Taimaha Molecular: 232.23

-te rewa: 37-39 ℃

-kohuatanga: 344-346 ℃

-Solubility: Ka whakarewahia i roto i nga whakarewa pararopi penei i te chloroform, te waiwaro me te dichloromethane, he paku memeha ki te wai.

Whakamahia:

- Ko te ethyl l he takawaenga whakahiato pararopi e whakamahia ana hei whakahiato i nga raau taero, nga homoni me nga hua taiao.

-Ka taea hoki te whakamahi hei taonga tohutoro mo te rangahau rongoa me te whakahiato raau taero.

Tikanga Whakaritenga:

Ko te ethyl te nuinga o te wa ka whakahiatohia e nga waahanga e whai ake nei:

1. Tuatahi, ka whakakapihia te methoxybenzofuran ki te waikawa bromoacetic kia whiwhi 5-methoxybenzofuran -2-acetic acid.

2. Na, ka tauhohehia te waikawa 5-methoxybenzofuran-2-acetic ki te thionyl chloride (SOCl2) hei huri hei waikawa chloride.

3. Ka mutu, ka tauhohehia te waikawa waikawa ki te waihano hei whakaputa i te ethyl phenyl.

Mōhiohio Haumaru:

- Ko te ethyl l he matū e tika ana te penapena me te whakahaere.

-He mea whakapataritari, me karo i te pa ki te kiri me nga kanohi. Mena ka pa mai, ka horoi tonu ki te wai maha ka rapu awhina hauora.

-I roto i te whakamahi, kia mau tonu tikanga ventilation pai, karo inhalation o hau me te kohu.
