1,2-Diethyl-5-ethoxycarbonyl-3-pyrazolidinone is a complex organic compound with the molecular formula C11H19NO3. It is a derivative of pyrazolidinone, which is a five-membered heterocyclic ring containing two nitrogen atoms. The compound features two ethyl groups (C2H5) attached to the first and second carbon atoms of the pyrazolidinone ring, an ethoxycarbonyl group (C2H5O2) connected to the fifth carbon, and a carbonyl group (C=O) at the third position. This chemical is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, owing to its unique structure and reactivity. Its properties, such as solubility and stability, can be influenced by the presence of these functional groups, making it a versatile building block in organic chemistry.
The CAS Registry Mumber 6442-59-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 2 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6442-59: (6*6)+(5*4)+(4*4)+(3*2)+(2*5)+(1*9)=97 97 % 10 = 7 So 6442-59-7 is a valid CAS Registry Number.
