"O,O'-dibenzoyl-tartaric acid diethyl ester" is a complex organic compound with the chemical formula C20H20O8. It is derived from tartaric acid, a naturally occurring organic acid, by esterification with diethyl and subsequent benzoylation. O,O'-dibenzoyl-tartaric acid diethyl ester is characterized by its chiral center, which gives it potential applications in the synthesis of optically active compounds. It is often used in the pharmaceutical industry for the preparation of chiral auxiliaries and as a building block in the synthesis of complex molecules. The compound's structure features two benzoyl groups attached to the tartaric acid core, with diethyl ester groups providing additional functionality. Its synthesis involves multiple steps, including protection of the tartaric acid hydroxyl groups, benzoylation, and esterification, which can be challenging due to the compound's sensitivity to reaction conditions. The compound's properties, such as solubility and reactivity, are influenced by its molecular structure, making it a valuable intermediate in organic synthesis.
The CAS Registry Mumber 4181-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 1 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4181-79: (6*4)+(5*1)+(4*8)+(3*1)+(2*7)+(1*9)=87 87 % 10 = 7 So 4181-79-7 is a valid CAS Registry Number.
