2-Methyl-4-trifluoromethyl-thiazole-5-carboxylic acid (CAS # 117724-63-7)

ʻO ka 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid he mea hoʻohuihui me ke ʻano kemika C6H4F3NO2S.

Loaʻa i ka hui nā waiwai penei:
1. Nānā: ke aniani kala ʻole a i ʻole ka pauka crystalline keʻokeʻo.
2. Ka helu heheʻe: ma kahi o 70-73 ° C.
3. Solubility: hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik, e like me ka ethanol, dimethyl sulfoxide a me ka chloroform, hiki ke hoʻoheheʻe iki i ka wai.

ʻO 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid nā mea hoʻohana nui:
1. kahua lāʻau lapaʻau: ma ke ʻano he lāʻau waena, hiki ke hoʻohana ʻia no ka synthesis o nā ʻano lāʻau lapaʻau.
2. kahua pesticide: hoʻohana mau ʻia i ka synthesis o nā pesticides hou, herbicides a me nā pesticides ʻē aʻe.

ʻO 2-methyl -4-(trifluoromethyl) thiazole -5-carboxylic acid nā ʻano hana hoʻomākaukau ʻo ia ka mea nui:
1. ka amide a me ka formaldehyde condensation pane: formic acid a me ka ethyl ester condensation e hoʻohua i ka waikawa anhydride, a laila me ka amine condensation pane e loaʻa ai ka huahana i manaʻo ʻia.
2. ʻO ka hoʻoheheʻe ʻana o ka wai ma lalo o ka waikawa catalysis: 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid i hoʻopili ʻia me ka hydrogen ma lalo o ka waikawa catalysis e loaʻa ai ka huahana i manaʻo ʻia.

E pili ana i ka ʻike palekana, ʻike pinepine ʻia ka ʻikepili toxicological a me ka palekana o ka 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid, no laila pono e mālama i kekahi mau mea palekana i ka wā o ka hana ʻana, e like me ke kau ʻana i nā aniani pale a me nā mīkina lima. e hōʻoia i ka hoʻokō ʻia ʻana o ka hana hoʻokolohua i loko o kahi kaiapuni maikaʻi. Eia kekahi, hiki ke hoʻopōʻino a hoʻonāukiuki ka mea hoʻohui, a pono e mālama ʻia e pale i ka pili ʻana me ka ʻili a me ka inhalation. I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e hahai ʻia nā kaʻina hana palekana kemika a mālama ʻia i kahi maloʻo, ventilated a me ka pouli. I ka lawelawe ʻana a me ka hoʻolei ʻana i kēia pūhui, e hahai i nā kānāwai kūloko kūpono a me nā alakaʻi hana palekana. Inā pili ʻole ʻoe i ka mea, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.
