"12-(2,4-dinitro-phenylhydrazono)-dodecanoic acid methyl ester" is a complex organic compound with the molecular formula C19H24N4O5. It is derived from dodecanic acid, a saturated fatty acid with a 12-carbon chain, and is characterized by the presence of a methyl ester group and a 2,4-dinitrophenylhydrazone moiety. The 2,4-dinitrophenylhydrazone group is formed by the reaction of the carbonyl group of the dodecanic acid with 2,4-dinitrophenylhydrazine, which is a common reagent used in organic chemistry for the detection and identification of aldehydes and ketones. 12-(2,4-dinitro-phenylhydrazono)-dodecanoic acid methyl ester is often used in analytical chemistry for the qualitative detection of aldehydes and ketones due to the distinct color it forms upon reaction. It is also important in the field of organic synthesis, where it can be used as an intermediate in the preparation of various pharmaceuticals and other chemical products.
The CAS Registry Mumber 3602-59-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,0 and 2 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3602-59: (6*3)+(5*6)+(4*0)+(3*2)+(2*5)+(1*9)=73 73 % 10 = 3 So 3602-59-3 is a valid CAS Registry Number.
