(+/-)-2,3-dimethyl-butyraldehyde-(2,4-dinitro-phenylhydrazone) is a chemical compound derived from the reaction between 2,3-dimethylbutyraldehyde and 2,4-dinitrophenylhydrazine. (+/-)-2,3-dimethyl-butyraldehyde-(2,4-dinitro-phenylhydrazone) is formed as a result of a condensation reaction, where the aldehyde group of 2,3-dimethylbutyraldehyde reacts with the hydrazine group of 2,4-dinitrophenylhydrazine, leading to the formation of a hydrazone linkage. The presence of the 2,4-dinitrophenyl group provides a distinct chromophore, which can be useful for spectroscopic analysis and identification purposes. The compound is a racemic mixture, indicating that it contains equal amounts of both the R and S enantiomers. This chemical is often used in organic synthesis and as a reagent in analytical chemistry for the detection and characterization of aldehydes and ketones.
The CAS Registry Mumber 2109-97-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 9 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2109-97: (6*2)+(5*1)+(4*0)+(3*9)+(2*9)+(1*7)=69 69 % 10 = 9 So 2109-97-9 is a valid CAS Registry Number.
