L-Threonine, N-[(phenylmethoxy)carbonyl]-, 4-nitrophenyl ester is a complex organic compound with the chemical formula C18H18N2O7. It is a derivative of the amino acid L-threonine, where the carboxylic acid group is esterified with a 4-nitrophenol group, and the amino group is protected by a phenylmethoxycarbonyl (PMC) group. L-Threonine, N-[(phenylmethoxy)carbonyl]-, 4-nitrophenyl ester is often used in peptide synthesis as a protected amino acid building block, allowing for the controlled formation of peptide bonds in the presence of other functional groups. The PMC group serves as a temporary protecting group for the amino group, preventing unwanted side reactions during the synthesis process. The 4-nitrophenyl ester group is used for monitoring the progress of the reaction due to its UV absorbance, and it can be easily removed under mild acidic conditions once the desired peptide bond is formed.

5249-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5249-62-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,4 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5249-62:
(6*5)+(5*2)+(4*4)+(3*9)+(2*6)+(1*2)=97
97 % 10 = 7
So 5249-62-7 is a valid CAS Registry Number.
