Air & Water Reactions
Water insoluble.
Reactivity Profile
1-Acetyl-2-phenylhydrazine is an amide and an amine. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition 1-Acetyl-2-phenylhydrazine emits toxic fumes.
Fire Hazard
Flash point data for 1-Acetyl-2-phenylhydrazine are not available. 1-Acetyl-2-phenylhydrazine is probably combustible.
Purification Methods
Crystallise the hydrazine from aqueous EtOH. [Beilstein 15 H 241.]
Check Digit Verification of cas no
The CAS Registry Mumber 114-83-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 114-83:
(5*1)+(4*1)+(3*4)+(2*8)+(1*3)=40
40 % 10 = 0
So 114-83-0 is a valid CAS Registry Number.

N-Methylimidazole (NMI) can act as a masked HCN in the synthesis of 1,3-disubstitued-1H-1,2,4-triazoles via a formal cycloaddition reaction of hydrazonoyl chloride with NMI. The product was proved to be formed via an initial nucleophilic substitution of hydrazonoyl chloride with NMI following cyclization and two sequential C-N bond cleavages. This journal is
The impact of cation structure upon the acidity of triazolium salts in dimethyl sulfoxide
Konstandaras, Nicholas,Dunn, Michelle H.,Guerry, Max S.,Barnett, Christopher D.,Cole, Marcus L.,Harper, Jason B.
supporting information, p. 66 - 75 (2019/12/26)
A series of triazolium salts, selected for their varying electronic and steric properties, were prepared and their pKa values were determined in DMSO at 25 °C using the bracketing indicator method. The effect of each systematic structural variation upon the acidity of the triazolium cation has been considered, in particular examining the effects of systematically altering electronic properties, quantified through the use of Hammett σ parameters. The first pKa value for an azolium salt that generates a mesionic carbene is also reported. These new data allow for the selection of appropriate bases for the deprotonation of such triazolium salts and the potential to correlate the pKa values determined herein with the nucleophilicity of the corresponding carbenes.

Paragraph 0011; 0013; 0014; 0015, (2018/07/30)
The invention relates to a synthesis method for organic synthesis of an intermediate acetyl phenylhydrazine. The method mainly includes the steps of: adding 3mol phenylhydrazine into a reaction container and 4-5mol p-iodoacetanilide into a reaction container, performing heating to 90-95DEG C, conducting reflux for 130-150min, lowering temperature to 10-15DEG C, filtering the crystal, conducting washing with a methylamine solution and a dichloromethane solution respectively, performing recrystallization in an ethanol solution, precipitating crystals, conducting filtration, and performing dehydration with a dehydrating agent, thus obtaining the finished product acetyl phenylhydrazine.
