Iodoform disimpan dalam ampul

Iodoform (juga dikenali sebagai triiodomethane ) ialah sebatian organoiodin dengan formula kimia CHI
3. Rupa fizikal iodoform ialah krostal bewarna kuning pucat, kristal, dengan bau yang menusuk dan tersendiri (dalam teks kimia lama, bau kadangkala dirujuk sebagai hospital, di mana sebatian itu masih biasa digunakan) dan, sama dengan kloroform, rasa manis. . Ia kadangkala digunakan sebagai pembasmi kuman .

Iodoform selalu disalah panggil sebagai karbon triiodida, [4] salah kerana "karbon triiodide" boleh bermakna CI
3 atau C[I
3], mengabaikan atom hidrogen dalam molekul iodoform, yang membayangkan karbon trivalen atau monovalen dalam iodoform, yang tidak betul. Daripada nama yang salah itu, nama yang betul bagi iodoform atau triiodomethane harus digunakan.
