(2RS,3SR)-3-amino-2-methylbutyric acid, also known as meso-2-aminobutyric acid or meso-2-amino-2-methylpropanoic acid, is a chiral amino acid with a molecular formula of C5H11NO2. It is a non-proteinogenic amino acid, meaning it is not found in proteins and is not synthesized by the body. (2RS,3SR)-3-amino-2-methylbutyric acid has two chiral centers, resulting in four possible stereoisomers, but the (2RS,3SR)-isomer is the meso form, which is a unique isomer that is not optically active due to the presence of an internal plane of symmetry. It is used in various biochemical and pharmaceutical applications, such as a building block for the synthesis of other compounds and as a research tool in studying enzyme specificity and chiral recognition.
The CAS Registry Mumber 3860-29-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,6 and 0 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3860-29: (6*3)+(5*8)+(4*6)+(3*0)+(2*2)+(1*9)=95 95 % 10 = 5 So 3860-29-5 is a valid CAS Registry Number.
