I-5-Trifluoromethyl-pyridine-2-carboxylic acidmethyl ester (CAS# 124236-37-9)

I-Methyl 5-trifluoromethylpyridine-2-carboxylate, eyaziwa nangokuthi i-TFP ester, iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:

Imvelo:
-Ukubukeka: uketshezi olungenambala
-Ifomula yemolekyuli: C8H4F3NO2
Isisindo samangqamuzana: 205.12g/mol
-Ukuminyana: 1.374 g/mL
-Indawo yokubilisa: 164-165°C

Sebenzisa:
- I-TFP esters isetshenziswa kabanzi ekuhlanganiseni kwe-organic kanye nocwaningo lwezemithi. Kuyiqembu elisebenzayo elimnandi elivikela i-reagent, elingasetshenziswa ukuvikela iqembu le-amino, iqembu le-hydroxyl kanye neqembu le-thioether.
-Ingasetshenziswa njengendawo ephakathi yemithi yokuhlanganiswa kwezakhi eziphilayo eziqukethe amaqembu e-trifluoromethyl.
-Ngaphezu kwalokho, i-ester ye-TFP ingabuye isetshenziselwe ukuhlanganiswa kwama-amide compounds, futhi isetshenziswa kabanzi ekucwaningweni kwamakhemikhali, kwezemithi kanye nezibulala-zinambuzane zokusabela kwe-ester exchange kanye nokuvikelwa kwe-amino.

Indlela Yokulungiselela:
- Ama-esters e-TFP angalungiswa ngokusabela i-trifluoromethylpyridine nge-methyl 2-formate. Ukusabela ngokuvamile kwenzeka ekamelweni lokushisa futhi umkhiqizo owufunayo ungahlanzwa nge-distillation.

Ulwazi Lokuphepha:
- I-ester ye-TFP ibhekwa njengephephile ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Kodwa-ke, njengenhlanganisela yezinto eziphilayo, kunengozi ethile engaba khona.
-Ukuthintana ngqo nesikhumba namehlo kungase kubangele ukucasuka noma ukulimala. Ngakho-ke, kufanele kuqashelwe ukugqoka izinto zokuzivikela ezifanele njengamagilavu ​​nezibuko ngesikhathi sokusetshenziswa.
-Ngaphezu kwalokho, i-ester ye-TFP kufanele futhi igcinwe kude nomlilo kanye nokushisa okuphezulu ukugwema umlilo noma ukuqhuma okungenzeka.

Ukuze uthole ulwazi oluthe xaxa lokusebenzisa nokuphepha, sicela uthintane nezincwadi zamakhemikhali ezifanele noma uthintane nochwepheshe.
