3-METHYL-5-ISOXAZOLEACETIC ACID（CAS#19668-85-0 ) Folasaga

3-METHYL-5-ISOXAZOLEACETIC ACID o se faʻalapotopotoga faʻapitoa faʻatasi ma le fua faʻamisi C6H7NO3. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu: Natura:
- Fa'aaliga: Pa'epa'e tioata malō
- Liu Liu: 157-160 ℃
-tele mole mole: 141.13g/mol
-Solubility: Soluble teisi i le vai, soluble i le ava malosi, eter ma solu vai
-O mea tau kemisi: 3-methyll-5-isoxazoleacetic ACID e mafai ona acylated, carbonylated ma suia e ACID-catalyzed reactions.

Fa'aaogā:
-Pharmaceutical field: 3-METHYL-5-ISOXAZOLEACETIC ACID o loʻo faʻaaogaina e avea o se mea faʻapipiʻi faʻapipiʻi ma e masani ona faʻaaogaina i le sauniuniga o vailaʻau ma meaola olaola.
-Pesticide fanua: E mafai foi ona faʻaaogaina e avea o se mea mataʻutia mo vailaau faʻasaina, faʻaaogaina e saunia ai vailaau faʻasaina, fungicides ma herbicides.

Metotia:
Ole auala ole sauniuniga ole 3-methyll-5-isoxazoleacetic ACID e sili atu ona faigata, ae e mafai ona faia i laasaga nei:
1. Sauni muamua le 5-Isoxazolylmethanol (5-Isoxazolylmethanol).
2. Faʻaaogaina o le pyruvic acid (Acetone) ma le potassium nitrate (Potassium nitrate) i le i ai o ionide iodide mo le faʻafefeteina o le faʻamaʻiina, saunia o le 5-Isoxazolylcarboxylic acid (5-Isoxazolylcarboxylic acid).
3. Acylation o le 5-isoxazolyl carboxylic ACID e faʻaaoga ai le methanol ma le sulfuric ACID e gaosia ai le 3-METHYL-5-ISOXAZOLEACETIC ACID.

Fa'amatalaga Saogalemu:
Pe a tagofia le 3-methyll-5-isoxazoleacetic ACID, e tatau ona faia ni puipuiga saogalemu:
- Aloese mai le fa'afeso'ota'i ma le pa'u ma mata. Afai e fa'afeso'ota'i, fufulu vave i le tele o vai.
- Fa'aaoga mea e puipui ai le tagata lava ia e pei o matatioata, totigilima ma ofu su'esu'e.
- Aloese mai le manavaina o lona ausa po o le pefu, ma ia lava le ea i le taimi o le taotoga.
-Pe a faʻatino sauniuniga faʻavae suʻesuʻe, mulimuli i faiga saogalemu a le falesuesue vailaʻau.
