Butanedioic acid, 2-ethyl-2-methyl, dimethyl ester, (S)-, also known as dimethyl 2-ethyl-2-methylsuccinate, is a chiral organic compound with the molecular formula C8H14O4. It is a derivative of butanedioic acid, featuring a 2-ethyl-2-methyl substituent and two methyl ester groups. Butanedioic acid, 2-ethyl-2-methyl-, dimethyl ester, (S)- is characterized by its asymmetric carbon atom, which gives rise to its (S)-enantiomeric form. It is used in the synthesis of various pharmaceuticals and agrochemicals, particularly as an intermediate in the production of chiral compounds. The compound's unique structure and properties make it valuable in the field of asymmetric synthesis and as a building block for more complex molecules.
The CAS Registry Mumber 4727-78-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 7 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4727-78: (6*4)+(5*7)+(4*2)+(3*7)+(2*7)+(1*8)=110 110 % 10 = 0 So 4727-78-0 is a valid CAS Registry Number.
