| Fa'amatalaga Saogalemu | S26 – Pe a pa'i i mata, fufulu vave i le tele o vai ma saili fautuaga fa'afoma'i. S37/39 – Fai totigilima talafeagai ma le puipuiga o mata/mata |
Folasaga
Ose fa'alapotopotoga fa'alenatura ma le fua fa'a-kemikolo C5H5N2O2. E masani lava e leai se lanu i le samasama samasama malō tioata.
O le tuufaatasiga e lua vaega aoga, tasi o se mama pyrazole ma le isi o se vaega galue carboxylic acid. E solubility feololo ma e soluble i le vai ma soluble masani masani. O le vaega methyl i lona fausaga e mafua ai le hydrophobic.
I le avea ai o se tuufaatasiga heterocyclic, 5-methyl-o loʻo i ai le tele o gaioiga faʻapitoa. E faʻaaogaina lautele i suʻesuʻega vailaʻau ma vailaʻau faʻapipiʻi, e masani lava o se mea mataʻutia poʻo se mea faʻapitoa. O fa'aoga fa'apitoa e aofia ai le tu'ufa'atasiga o vaitamini B1 analogs, insecticides, plavix inhibitors (o se mea fa'aoga e taofia ai le tuputupu a'e o laau), ma isi mea faapena.
Sauniuniga, 5-methyl-e mafai ona maua e ala i le taliina o le atom nitrogen o le mama pyrazole ma se sui methylating (eg methyl iodide). O lenei metotia o loʻo faʻatinoina e se tali N-methylation, o le auala masani o le tali atu o le nucleophile tutusa ma se N-methyl reagent.
