• Chemische Eigenschaften

  White moist crystals and chunks

• Verwenden

  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.

• Definition

  ChEBI: A carbohydrazide that is hydrazine in which one of the hydrogens is replaced by an acetyl group.

• Sicherheitsprofil

  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,.

• Synthese

  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.

• läuterung methode

  Acetic hydrazide crystallises as needles from EtOH. It reduces NH3/AgNO3. [Beilstein 2 H 191, 2 IV 435.]
