Hoʻolauna

ʻO 2-Methylthio-3-methylpyrazine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

1. Nānā: 2-methylthio-3-methylpyrazine maʻamau keʻokeʻo a i ʻole crystalline, a ma ke ʻano he pauka.

2. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me chloroform, benzene, a me ethanol.

 

E hoʻohana:

1. Pesticides: Hiki ke hoʻohana ʻia ka 2-methylthio-3-methylpyrazine e like me nā fungicides a me nā insecticides, a he hopena maikaʻi ʻo ia i nā haʻuki a me nā pests ma kekahi mau mea kanu.

2. Kemika moana: Hiki ke hoʻohana ʻia kēia pūhui i ka noiʻi kai e aʻo i ka ʻano a me nā pane physiological o nā meaola kai.

 

Hanana:

Hiki ke hoʻohui ʻia ʻo 2-Methylthio-3-methylpyrazine e nā pae aʻe:

1. E hoʻohuihui i ka methyl thiocyanate a me ka acetone ma lalo o nā kūlana kūpono e hana i nā ʻano like ʻole Kawasaki.

A laila, hoʻopili ʻia ka Kawasaki heterocycle me ka waika formic e hāʻawi i ka 2-methylthio-3-methylpyrazine.

 

ʻIke palekana:

1. He hopena hoʻonāukiuki ka 2-Methylthio-3-methylpyrazine a pono e paleʻia mai ka piliʻana me kaʻili a me nā maka.

2. Pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima a me nā maka aniani i ka wā e hoʻohana ai a lawelawe ʻia paha.

3. Ina inhaled a inested, e imi koke i ke kauka.
