1-Methyl-2-indanon-<2,4-dinitro-phenylhydrazon> is a complex organic compound with the molecular formula C16H14N4O4. It is derived from the parent compound 1-methyl-2-indanon, which is a derivative of indanone, a cyclic ketone. The 2,4-dinitro-phenylhydrazone functional group is formed by the reaction of the ketone with 2,4-dinitrophenylhydrazine, resulting in the formation of a hydrazone bond. 1-Methyl-2-indanon-<2,4-dinitro-phenylhydrazon> is characterized by its yellow crystalline appearance and is used as a reagent in chemical analysis and synthesis. It is important to note that due to the presence of nitro groups, 1-Methyl-2-indanon-<2,4-dinitro-phenylhydrazon> may be sensitive to heat and shock, and should be handled with care.
The CAS Registry Mumber 3199-91-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 9 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3199-91: (6*3)+(5*1)+(4*9)+(3*9)+(2*9)+(1*1)=105 105 % 10 = 5 So 3199-91-5 is a valid CAS Registry Number.
