Valine-(4-nitro-phenyl ester); hydrobromide is a chemical compound with the molecular formula C12H14BrNO4. It is a derivative of the amino acid valine, where the carboxylic acid group is esterified with 4-nitrophenol, and the compound is then protonated with hydrobromic acid to form the hydrobromide salt. valine-(4-nitro-phenyl ester); hydrobromide is often used in organic synthesis and as a reagent in various chemical reactions, particularly in the preparation of pharmaceuticals and other bioactive molecules. The 4-nitrophenyl ester group serves as a protecting group for the carboxylic acid, which can be removed under specific conditions to regenerate the free acid. The hydrobromide salt form enhances the solubility and stability of the compound in certain solvents, making it a useful intermediate in the synthesis of valine-containing compounds.

7797-27-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7797-27-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 7797-27:
(6*7)+(5*7)+(4*9)+(3*7)+(2*2)+(1*7)=145
145 % 10 = 5
So 7797-27-5 is a valid CAS Registry Number.
