3-Pentenal 2,4-dinitrophenyl hydrazone is a chemical compound derived from the reaction between 3-pentenal, an aldehyde with a five-carbon chain, and 2,4-dinitrophenyl hydrazine, a reagent used for the detection and identification of aldehydes and ketones. 3-pentenal 2,4-dinitrophenyl hydrazone is formed through a condensation reaction, where the carbonyl group of 3-pentenal reacts with the hydrazine group of 2,4-dinitrophenyl hydrazine, resulting in the formation of a hydrazone linkage. The 2,4-dinitrophenyl group serves as a chromophore, providing a distinct yellow color to the compound, which can be used for qualitative analysis. The formation of this hydrazone derivative is indicative of the presence of an aldehyde group in the original 3-pentenal molecule, and the compound itself is often used in organic chemistry for the detection and characterization of aldehydes.

5558-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5558-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 5558-20:
(6*5)+(5*5)+(4*5)+(3*8)+(2*2)+(1*0)=103
103 % 10 = 3
So 5558-20-3 is a valid CAS Registry Number.
