Sintesis Dan Uji Toksisitas 6-(4-Klorofenil)-4,5- Dihidropiridazin-3(2h)-On
Pyridazinone is a heterocyclic dinitrogen compound with one carbonyl which is known to have diverse biological activities such as anticonvulsant, analgesic, anti inflammatory, anti microbial, and anti hypertension. The pyridazinone 6-(4-chlorophenyl)pyridazin-3(2H)-one synthesized with 4-chloro acetophenone, glyoxylic acid and hydrazine hydrate by sealed-vessel reactor method. The purity of the pyridazinone was determined by the TLC test, determination of melting point, and HPLC analysis. The structure of the pyridazinone was obtained from UV, FTIR, NMR, and HRMS spectroscopic studies. Synthesis of 6-(4-chlorophenyl)-4,5dihydropyridazin-3(2H)-one in this research was concluded with a yield 60,52%, and the toxicity was determined by the Brine Shrimp Lethality Test (BSLT) method. The value of the LC50 was showed 7,01 µg/mL. From the data above was concluded that 6-(4-chlorophenyl)-4,5-dihydropyridazin-3(2H)-one conjugate was toxic.
