Folasaga

2-Methylthio-4-pyrimidinone o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:

 

Tulaga lelei:

- Fa'aaliga: 2-Methylthio-4-pyrimidinone ose malo o tioata e leai ni lanu po'o pa'epa'e tioata pa'epa'e.

- Solubility: E maualalo le soluble i le vai ae sili atu le solubility i soluble organic pei ole ethanol ma le dimethyl sulfoxide.

- Fa'a'ai vaila'au: 2-methylthio-4-pyrimidinone e mafai ona tali atu i isi mea fa'afefiloi e ala i gaioiga fa'ama'i e pei ole sulfonation, sui, ma le cycloaddition.

 

Fa'aaogā:

- Pesticide: 2-methylthio-4-pyrimidinone ose vailaʻau taua ma herbicide intermediate, faʻaaogaina lautele i le fanua faʻatoʻaga.

- La'au felanulanua'i: E mafai fo'i ona fa'aogaina e fai ma mea fa'alili felanulanua'i ma fa'aigoa fa'ailoga, fa'atasi ai ma le avanoa e fa'ata'ita'i ma iloa ai i su'esu'ega fa'alesoifua maloloina.

 

Metotia:

- 2-Methylthio-4-pyrimidinone e mafai ona saunia e ala i le tali atu o le 2-methylthio-4-aminoimidazole ma ketones i lalo o tulaga faʻamaʻi.

 

Fa'amatalaga Saogalemu:

- 2-Methylthio-4-pyrimidinone ose fa'alapotopotoga fa'alenatura ma nisi oona. O faiga e puipuia ai le tagata lava ia, e pei o totigilima, mata tioata, ma lavalava puipui, e tatau ona faia pe a faʻaoga pe faʻafesoʻotaʻi.

- O le fa'afeso'ota'i ma le pa'u po'o le manavaina o lona pefu e ono fa'atupu ai le fa'ama'i po'o le ita, ma e tatau ona 'alofia le fa'aumi umi po'o le manava tele.

- I le taimi o le teuina ma le tagofiaina, e tatau ona faʻaeteete e aloese mai le faʻafesoʻotaʻi ma vailaʻau faʻamaʻi, vailaʻau malosi, ma isi mea e aloese ai mai faʻalavelave mataʻutia.

- Pe a lafoai otaota, e tatau ona lafoai e tusa ai ma tulafono faatonutonu talafeagai e aloese ai mai le faaleagaina o le siosiomaga.
