3-methyl-1-phenyl-butan-1-one-(2,4-dinitro-phenylhydrazone) is a complex organic compound that can be derived from the parent ketone, 3-methyl-1-phenyl-butan-1-one, through a reaction with 2,4-dinitrophenylhydrazine. This derivative is often used in analytical chemistry for the detection and identification of ketones due to the distinct color it forms upon reaction. The compound features a butanone core with a methyl group at the third carbon, a phenyl group attached to the first carbon, and a 2,4-dinitrophenylhydrazone moiety. The 2,4-dinitrophenylhydrazone group is characterized by two nitro groups at the 2 and 4 positions of a phenyl ring, which is connected to the hydrazone functional group. 3-methyl-1-phenyl-butan-1-one-(2,4-dinitro-phenylhydrazone) is significant in organic synthesis and can be used to study the properties of ketones and their derivatives, as well as in the development of analytical methods for detecting ketones in various samples.
The CAS Registry Mumber 2891-48-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 1 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2891-48: (6*2)+(5*8)+(4*9)+(3*1)+(2*4)+(1*8)=107 107 % 10 = 7 So 2891-48-7 is a valid CAS Registry Number.
