-Kunyungudika nzvimbo: anenge 116-118 madhigirii Celsius.
Shandisa:
-must acid inowanzoshandiswa sechinhu chakakosha chepakati mune organic synthesis.
-Inogona kushandiswa kugadzira organic komisheni ine thiophene mhete zvimiro.
Kugadzirira Nzira: Kune dzakawanda nzira dzekugadzira dze
-anacid. Imwe yenzira dzinowanzo shandiswa ndeye kushandisa bromoacetic acid seyakabikwa, kuita ne thiophene pasi pemamiriro ealkaline kugadzira 3-bromothiophene, uyezve kuita carboxylic reaction pasi pemamiriro ane acidic.
Zvekuchengetedza
-iyo asidhi inogona kushungurudza maziso, ganda uye hurongwa hwekufema.
-Panguva yekushandiswa, kutarisirwa kunofanira kutorwa kuti usafemerwa neguruva kana kusangana neganda nemeso.
-Pfeka midziyo yekudzivirira yakakodzera senge magurovhosi erabhoritari, magirazi uye zvivharo zvechiso usati washanda.
-Kana ukasangana neganda kana maziso, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa. Matanho akakodzera erubatsiro rwekutanga achapihwa kana zvichidikanwa.
