3-METHYL-5-ISOXAZOLEACETIC ACID（CAS#19668-85-0)
-Ke ʻano: Paʻa keʻokeʻo keʻokeʻo
-Ka helu hehee: 157-160 ℃
-pili molecular mass: 141.13g/mol
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka waiʻona, ether a me nā mea hoʻoheheʻe organik
-Nā waiwai kemika: 3-methyll-5-isoxazoleacetic ACID hiki ke acylated, carbonylated a pani ʻia e ACID-catalyzed reactions.
E hoʻohana:
-Pharmaceutical kahua: 3-METHYL-5-ISOXAZOLEACETIC ACID ua hoʻohana ʻia ma ke ʻano he synthetic intermediate a hoʻohana maʻamau i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau a me nā moleke ola biologically.
-Pesticide kahua: Hiki ke hoʻohana ʻia e like me ka mea maka no nā pesticides, hoʻohana ʻia e hoʻomākaukau i nā pesticides, fungicides a me nā herbicides.
Hanana:
ʻOi aku ka paʻakikī o ka hoʻomākaukau ʻana o 3-methyll-5-isoxazoleacetic ACID, akā hiki ke hana ʻia ma o nā pae aʻe:
1. E hoʻomākaukau mua i ka 5-Isoxazolylmethanol (5-Isoxazolylmethanol).
2. Ke hoʻohana nei i ka pyruvic acid (Acetone) a me ka Potassium nitrate (Potassium nitrate) i mua o nā ionide iodide no ka hopena nitration, hoʻomākaukau i ka 5-Isoxazolylcarboxylic acid (5-Isoxazolylcarboxylic acid).
3. Acylation o 5-isoxazolyl carboxylic ACID e hoʻohana ana i ka methanol a me ka sulfuric ACID e hana i ka 3-METHYL-5-ISOXAZOLEACETIC ACID.
ʻIke palekana:
I ka lawelawe ʻana i ka 3-methyll-5-isoxazoleacetic ACID, pono e mālama ʻia kēia mau mea palekana:
-E pale i ka pili me ka ʻili a me nā maka. Inā pili, holoi koke me ka wai nui.
-E hoʻohana i nā lako pale pilikino kūpono e like me nā maka aniani, nā mīkina lima a me nā lole lab.
-E hōʻalo i ka hanu ʻana i kona mahu a i ʻole ka lepo, a hāʻawi i ka ea i ka wā e hana ai.
-I ka hana ʻana i ka hoʻomākaukau ʻana i ka pālākiō, e hahai i nā hana palekana o ka hale kemika.
