2,4-Dinitrophenylhydrazine (CAS: 119-26-6), turunan hidrazin, minangka senyawa C-nitro sing fenilhidrazin diganti ing posisi 2 lan 4 dening gugus nitro.Iki nduweni peran minangka reagen.Iki minangka anggota fenilhidrazin lan senyawa C-nitro.Lan aldehida, reaksi keton abang kuning.Iku gampang kobong lan beracun.Jeblugan nalika garing.Mbebayani nalika dihirup, ditelan utawa kena kulit.Digunakake minangka agen kromogenik kanggo nemtokake aldehida lan keton kanthi fotometri lan kanggo nemtokake aldehida lan keton kanthi kromatografi lapisan tipis.2,4-Dinitrophenylhydrazine wis digunakake minangka reagen kanggo ndeteksi anané aldehida lan keton ing karbonil protein.Bisa digunakake minangka reagen colorimetric ing estimasi kuantitatif prednison.
Dinitrophenylhydrazine relatif sensitif marang kejut lan gesekan;iku mbledhos kejut supaya care kudu dijupuk karo nggunakake.Biasane diwenehake udan kanggo nyuda bebaya bledosan.Iki minangka hidrazin sing diganti, lan asring digunakake kanggo uji kualitatif kanggo gugus karbonil sing ana gandhengane karo aldehida lan keton.Turunan hidrazon uga bisa digunakake minangka bukti kanggo identitas senyawa asli.Dinitrophenylhydrazine ora bereaksi karo gugus fungsi karbonil liyane kayata asam karboksilat, amida, lan ester.Kanggo asam karboksilat, amida lan ester, ana stabilitas sing ana hubungane karo resonansi nalika pasangan elektron tunggal berinteraksi karo orbital p karbonil karbonil sing nyebabake delokalisasi molekul.Stabilitas iki bakal ilang kanthi nambahake reagen ing gugus karbonil.
