[(2S,3S)-2-((S)-2-Benzyloxycarbonylamino-propionylamino)-3-methyl-pentanoylamino]-acetic acid ethyl ester is a complex organic compound with the molecular formula C22H33N2O6. It is a chiral molecule, containing two stereocenters (2S, 3S), and is an ester derivative of a pentanoic acid. The compound features a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to protect the amino group. The structure also includes a propionylamino group, indicating the presence of a propionyl moiety attached to an amino group. [(2S,3S)-2-((S)-2-Benzyloxycarbonylamino-propionylamino)-3-methyl-pentanoylamino]-acetic acid ethyl ester is likely used in the synthesis of peptides or other biologically active molecules, where the protecting group can be removed under specific conditions to reveal the free amino group, facilitating further reactions or the formation of peptide bonds.
The CAS Registry Mumber 2682-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 2 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2682-71: (6*2)+(5*6)+(4*8)+(3*2)+(2*7)+(1*1)=95 95 % 10 = 5 So 2682-71-5 is a valid CAS Registry Number.
