2-(2,4-dinitro-phenylhydrazono)-4-hydroxy-valeraldehyde-(2,4-dinitro-phenylhydrazone) is a complex organic compound with the molecular formula C11H10N6O5. It is a derivative of valeraldehyde, an aldehyde with a five-carbon chain, which has been modified by the addition of two 2,4-dinitrophenylhydrazone groups. These groups are attached to the aldehyde's carbonyl group and a hydroxyl group, forming a hydrazone linkage. 2-(2,4-dinitro-phenylhydrazono)-4-hydroxy-valeraldehyde-(2,4-dinitro-phenylhydrazone) is often used in analytical chemistry as a reagent for the detection and quantification of aldehydes and ketones due to its ability to form colored complexes with these compounds. The presence of the 2,4-dinitrophenylhydrazone groups enhances the stability and solubility of the complex, making it a valuable tool in various chemical analyses.
The CAS Registry Mumber 13137-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,3 and 7 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 13137-41: (7*1)+(6*3)+(5*1)+(4*3)+(3*7)+(2*4)+(1*1)=72 72 % 10 = 2 So 13137-41-2 is a valid CAS Registry Number.
