Hex-3c-enal-(2,4-dinitro-phenylhydrazone) is a chemical compound derived from the reaction between hex-3-enal, an aldehyde with a six-carbon chain, and 2,4-dinitrophenylhydrazine, a reagent used for the detection and identification of aldehydes and ketones. hex-3c-enal-(2,4-dinitro-phenylhydrazone) is formed through a condensation reaction, where the carbonyl group of hex-3-enal reacts with the hydrazine group of 2,4-dinitrophenylhydrazine, resulting in the formation of a hydrazone linkage. The 2,4-dinitrophenylhydrazone derivative is often used in analytical chemistry for the qualitative and quantitative determination of aldehydes, as it provides a stable, colored product that can be easily separated and analyzed. The compound is characterized by its yellow color and can be used to confirm the presence of aldehydes in various samples, such as biological fluids or environmental samples.
The CAS Registry Mumber 2121-99-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2121-99: (6*2)+(5*1)+(4*2)+(3*1)+(2*9)+(1*9)=55 55 % 10 = 5 So 2121-99-5 is a valid CAS Registry Number.
