(2R,3R)-3-Amino-2-methyl-butyric acid methyl ester is a chiral amino acid derivative with the molecular formula C6H13NO2. It is an optically active compound, meaning it exists in two enantiomeric forms, with the (2R,3R) configuration being one of them. (2R,3R)-3-Amino-2-methyl-butyric acid methyl ester is characterized by a methyl group at the 2nd carbon, an amino group at the 3rd carbon, and a methyl ester group at the carboxylic acid end. It is synthesized by esterification of the corresponding (2R,3R)-3-amino-2-methylbutyric acid with methanol. This chiral compound has potential applications in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals, where the stereochemistry plays a crucial role in determining the biological activity of the final product.
The CAS Registry Mumber 28763-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,6 and 3 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 28763-09: (7*2)+(6*8)+(5*7)+(4*6)+(3*3)+(2*0)+(1*9)=139 139 % 10 = 9 So 28763-09-9 is a valid CAS Registry Number.
