-relative massa hypothetica: 141.13g/mol
-Solubility: Leviter solutum in aqua, solutum in alcohole, aethere et organicis solventibus
-Chemicae proprietates: 3-methylli-5-isoxazoleaceticae ACID acylated, carbonylated et substituti per reactiones ACID-catalytici.
Utere:
-Pharmaceuticus campus: 3-METHYL-V-ISOXAZOLEACETICUS ACID synthetica media adhibetur et communiter adhibetur in praeparatione medicamentorum et moleculis biologice activis.
-Pesticide campus: adhiberi potest etiam ut materia cruda pesticides, ad praeparandas pesticides, fungicides et herbicides.
Modus:
Praeparatio methodi 3-methylli-5-isoxazoleacetici ACID magis complicata est, sed perfici potest per gradus sequentes:
1. Praeparet primum 5-Isoxazolylmethanol (5-Isoxazolylmethanol).
2. Acidum pyruvicum (acetone) et nitratum potassium (nitrate potassium) coram iodidum ad reactionem nitrationis, praeparatio acidi 5-Isoxazolylcarboxylici (accidi Isoxazolylcarboxylici).
3. Acylatio 5-isoxazolyl ACID carboxylici utens methanolum et ACIDUM sulphuricum ad generandum 3-METHYL-5-ISOXAZOLEACETICUM ACIDUM.
Salus Information:
Cum tractandis 3-my- 5-isoxazoleaceticis ACIDUM, cavendum est ut salutem sequentes;
- Fuge contactum cum cute et oculis. Si contactus incidit, statim abluam multa aqua.
-Gesta commoda propria armorum tutela ut goggles, caestus et lab tunicas.
- Fuge attrahentem vaporem vel pulverem, et praebeat congruam evacuationem in operatione.
- Cum praeparationes laboratoriae faciendo, securas exercitationes laboratorium chemicum sequere.
