4-Fluorobenzhydrazide Usage And Synthesis

preparation

The synthesized ester (12.5ml) was taken into a round  bottom flask (250ml), 50ml of absolute ethanol &  37.5ml of hydrazine hydrate was added in the flask.  The ester, ethanol & hydrazine hydrate for the synthesis of hydrazide must be in following ratio: Ester: Absolute ethanol: Hydrazine hydrate 1 : 4 : 3  Then round bottom flask was covered with aluminium  foil, placed on hot plate & allowed to stir it for almost  12-15 hrs. As the solid product appeared, reaction  completion was checked by performing TLC using n-hexane, ethyl acetate & TLC cards & observed under  UV lamp. After completion of reaction n-hexane was added.  Solution filtered as needle like crystals appeared.  Allowed it to dry & a shiny off white product was  obtained that was hydrazide & product was calculated  (79%).
