α-Keto-azelainsaeure-dimethylester-2,4-dinitrophenylhydrazon is a complex organic compound with the chemical formula C12H14N4O5. It is derived from α-keto-azelaic acid, an organic compound with the formula C9H14O5, and is formed by the reaction of α-keto-azelaic acid with 2,4-dinitrophenylhydrazine, a reagent used for the detection and identification of aldehydes and ketones. The resulting hydrazone derivative is a yellow crystalline solid, which is soluble in organic solvents. α-Keto-azelainsaeure-dimethylester-2,4-dinitrophenylhydrazon is primarily used in analytical chemistry for the qualitative and quantitative determination of α-keto acids, as the formation of the hydrazone derivative allows for easier detection and quantification of these compounds in various samples.
The CAS Registry Mumber 18283-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,8 and 3 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 18283-18: (7*1)+(6*8)+(5*2)+(4*8)+(3*3)+(2*1)+(1*8)=116 116 % 10 = 6 So 18283-18-6 is a valid CAS Registry Number.
