2-Cyclopenten-1-one (2,4-dinitrophenyl)hydrazone is a chemical compound with the molecular formula C11H10N4O4. It is a derivative of cyclopentenone, featuring a hydrazone functional group formed by the reaction of 2-cyclopenten-1-one with 2,4-dinitrophenylhydrazine. This yellow crystalline solid is known for its potential applications in organic synthesis and as a reagent in chemical analysis. The compound exhibits a molecular weight of 258.22 g/mol and has a melting point of approximately 198-200°C. Its chemical structure is characterized by a cyclopentenone ring with a 2,4-dinitrophenyl group attached to the nitrogen atom of the hydrazone moiety. Due to the presence of nitro groups, 2-Cyclopenten-1-one (2,4-dinitrophenyl)hydrazone may possess explosive properties and should be handled with caution.

Check Digit Verification of cas no

The CAS Registry Mumber 789-99-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 789-99:
(5*7)+(4*8)+(3*9)+(2*9)+(1*9)=121
121 % 10 = 1
So 789-99-1 is a valid CAS Registry Number.

Synthesis of Allylazo Compounds by Reactions of Aryldiazonium Salts with Allylsilanes

Mayr, Herbert,Grimm, Klaus

, p. 1057 - 1059 (2007/10/02)

Aryldiazonium tetrafluoroborates react with allylsilanes to yield allylazo compounds.If the allylic carbon attached to the azo group carries hydrogen, tautomerization with formation of hydrazones takes place.
