In this research. the synthesis of a new azine derivative with coumarin moiety was performed in three reaction steps. starting from 4-hydroxycoumarin. The first step in synthesis was the acetylation of 4-hydroxycoumarin to yield 3-acetyl-4-hydroxycoumarin and then the obtained 3-acetyl-4-hydroxycoumarin was reacted with hydrazine hydrate and give a corresponding hydrazone. https://www.jmannino.com/super-price-NeoPure-Inline-Carbon-Block-1m-CTO-Lead-Cysts-10-x-2-5-1-4-Push-Connect-best-mega/
