2-Methyl-4-trifluoromethyl-thiazole-5-carboxylic acid (CAS# 117724-63-7)
2-methyl -4- (trifluoromethyl) thiazole-5-carboxylic acid ndi organic pawiri ndi mankhwala chilinganizo C6H4F3NO2S.
Chopangacho chili ndi zinthu zotsatirazi:
1. Maonekedwe: kristalo wopanda mtundu kapena ufa woyera wa crystalline.
2. Malo osungunuka: pafupifupi 70-73°C.
3. solubility: sungunuka mu zosungunulira organic, monga Mowa, dimethyl sulfoxide ndi chloroform, sungunuka pang'ono m'madzi.
2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid ntchito zazikulu zikuphatikizapo:
1. mankhwala munda: monga mankhwala wapakatikati, angagwiritsidwe ntchito kwa synthesis zosiyanasiyana mankhwala.
2. Malo ophera tizilombo: omwe amagwiritsidwa ntchito kwambiri popanga mankhwala atsopano, mankhwala a herbicides ndi mankhwala ena ophera tizilombo.
2-methyl -4-(trifluoromethyl) thiazole -5-carboxylic acid kukonzekera njira makamaka zotsatirazi:
1. amide ndi formaldehyde condensation reaction: formic acid ndi ethyl ester condensation kupanga asidi anhydride, ndiyeno ndi amine condensation reaction kuti apeze chandamale mankhwala.
2. Hydrogenation reaction pansi pa asidi catalysis: 2-methyl -4- (trifluoromethyl) thiazole-5-carboxylic acid imayendetsedwa ndi haidrojeni pansi pa catalysis ya asidi kuti ipeze mankhwala omwe akukhudzidwa.
Ponena za chitetezo, chidziwitso cha toxicological ndi chitetezo cha 2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid sichimanenedwa kawirikawiri, chifukwa chake ndikofunikira kusamala pochita opaleshoni ya labotale, monga kuvala magalasi oteteza ndi magolovesi, kuonetsetsa kuti ntchito yoyesera ikuchitika pamalo abwino mpweya wabwino. Kuonjezera apo, mankhwalawa akhoza kukhala owononga komanso okwiyitsa, ndipo ayenera kusamala kuti asagwirizane ndi khungu ndi kupuma. Pogwiritsa ntchito ndi kusunga, njira zotetezera mankhwala ziyenera kutsatiridwa ndikusungidwa pamalo owuma, mpweya wabwino komanso wamdima. Pogwira ndi kutaya pagululi, tsatirani malamulo oyenerera amderali komanso malangizo ogwiritsira ntchito moyenera. Ngati mwakumana ndi mankhwalawa mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.
