2-Pentenal 2,4-dinitrophenyl hydrazone is a chemical compound derived from the reaction between 2-pentenal, an aldehyde with a five-carbon chain, and 2,4-dinitrophenyl hydrazine, a reagent used in the formation of hydrazones. 2-pentenal 2,4-dinitrophenyl hydrazone is formed through a condensation reaction, where the carbonyl group of 2-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, which can be used for the detection and quantification of aldehydes in various analytical techniques. The compound is often used in organic synthesis and as a reagent in chemical analysis, particularly in the identification of aldehydes due to its distinct color and stability.
The CAS Registry Mumber 1576-90-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 6 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1576-90: (6*1)+(5*5)+(4*7)+(3*6)+(2*9)+(1*0)=95 95 % 10 = 5 So 1576-90-5 is a valid CAS Registry Number.
