Acethydrazide is an essential organic intermediate mainly used to synthesize nifuratrone in the pharmaceutical industry. It belongs to the hydrazine/hydrazone group, which plays an important role in the anti-microbial activity. Recently, Acethydrazide has gained significant importance due to its anti-tuberculosis activity. A disease caused by parasites represents a major world health problem with limited therapeutic options. Acethydrazide was synthesized from the reaction between ethyl acetate and hydrazine hydrate in methanol solvent and purified[1-2].

Acetic hydrazide is used as an antibiotic for the treatment of mycobacterium tuberculosis. It is also involved in the preparation of sunitinib b reacting with 5-fluoroisatin. Further, it inhibits mycolic acid biosynthesis. It serves as an important intermediate in organic synthesis such as nitric furosemide Long (nifuratrone) in medicine.
Acethydrazide can be used in the synthesis of (E)-N′-(2-hydroxybenzylidene)acetohydrazide, an ONO pincer ligand.
ChEBI: A carbohydrazide that is hydrazine in which one of the hydrogens is replaced by an acetyl group.
Poison by ingestion, subcutaneous, and intraperitoneal routes. Mutation data reported. Exposure can cause hemolysis and liver damage. See also PHENYLHYDRAZINE. When heated to decomposition it emits toxic fumes of NOX,.
A kind of preparation method of acethydrazide include the following steps: Under nitrogen protection, by acetic
acid, hydrazine hydrate
It is put into catalyst in the reaction kettle with rectifying column,
opens stirring, be heated to reflux, after steam enters rectifying
column,
Vapor are produced in tower top temperature for 98°C~100°C, when
reaction 4~6 is small at a reflux temperature, when rectifying tower
top frozen-free current
Reaction terminates after going out, and continues heating distillation,
and the acetic acid and hydrazine hydrate of reaction are had neither
part nor lot in 100°C~120°C extraction of tower top temperature,
After acetic acid and hydrazine hydrate are all steamed, liquid in
kettle is poured out into filtering while hot, filtrate is through
crystallisation by cooling, pure water, very
Acethydrazide finished product is obtained after sky is dry.
Acetic hydrazide crystallises as needles from EtOH. It reduces NH3/AgNO3. [Beilstein 2 H 191, 2 IV 435.]
