Propanedioic acid, (2-methylbutyl)-, diethyl ester, (S)-, also known as (S)-2-methylbutyl diethyl malonate, is a chiral organic compound with the molecular formula C10H20O4. It is a derivative of malonic acid, where the hydrogen atoms are replaced by a 2-methylbutyl group and two ethyl ester groups. Propanedioic acid, (2-methylbutyl)-, diethyl ester, (S)- is a colorless liquid with a density of 0.96 g/cm3 and a boiling point of 228-230°C. It is soluble in most organic solvents and has a mild, ester-like odor. (S)-2-methylbutyl diethyl malonate is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Its chiral nature makes it a valuable building block in the preparation of enantiomerically pure compounds, which is crucial in many applications due to the different biological activities of enantiomers.
The CAS Registry Mumber 6210-82-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,1 and 0 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6210-82: (6*6)+(5*2)+(4*1)+(3*0)+(2*8)+(1*2)=68 68 % 10 = 8 So 6210-82-8 is a valid CAS Registry Number.
