Hoʻolauna

ʻO 2-Methylthio-4-pyrimidinone he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2-Methylthio-4-pyrimidinone he paʻa o nā kelika kala ʻole a i ʻole nā ​​pauka crystalline keʻokeʻo.

- Solubility: He haʻahaʻa ka solubility i ka wai akā ʻoi aku ka maikaʻi o ka solubility i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethyl sulfoxide.

- Nā hopena kemika: Hiki i ka 2-methylthio-4-pyrimidinone ke hana me nā mea hoʻohui ʻē aʻe ma o nā hopena kemika e like me ka sulfonation, substitution, a me cycloaddition.

 

E hoʻohana:

- Pesticide: ʻO 2-methylthio-4-pyrimidinone ka mea nui insecticide a me ka herbicide intermediate, hoʻohana nui ʻia i ka māla mahiʻai.

- Hiki ke hoʻohana ʻia e like me nā mea hoʻonanea fluorescent a me nā reagents lepili, me ka hiki ke kiʻi a ʻike i ka noiʻi biomedical.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 2-Methylthio-4-pyrimidinone e ka hopena o 2-methylthio-4-aminoimidazole a me nā ketones ma lalo o nā kūlana acidic.

 

ʻIke palekana:

- ʻO ka 2-Methylthio-4-pyrimidinone he hui lāʻau me kekahi mea ʻona. Pono e lawe ʻia nā hana pale pilikino kūpono, e like me nā mīkina lima, nā maka aniani, a me nā lole pale i ka wā e hoʻohana ai a pili paha.

- ʻO ka pili ʻana me ka ʻili a i ʻole ka inhalation o kona lepo e hoʻoulu ai i ka maʻi a i ʻole ka huhū, a e pale ʻia ka lōʻihi a i ʻole ka inhalation nui.

- I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika, a me nā mea ʻē aʻe e pale aku i nā hopena pōʻino.

- I ka wā e hoʻolei ai i ka ʻōpala, pono e hoʻolei ʻia e like me nā lula kūpono e pale aku ai i ka haumia i ke kaiapuni.
