4-iodo-(L)-phenylalanine, tert-butyl ester hydrochloride is a chemical compound with the molecular formula C14H18ClINO2. It is a derivative of the amino acid L-phenylalanine, featuring an iodine atom at the 4-position of the phenyl ring and a tert-butyl ester group protecting the carboxylic acid group. The hydrochloride salt form is obtained by treating the compound with hydrochloric acid, which protonates the free amine group, enhancing its solubility in water. 4-iodo-(L)-phenylalanine, tert-butyl ester hydrochloride is often used in organic synthesis, particularly in the preparation of pharmaceuticals and other bioactive molecules, due to its unique structural features. The presence of the iodine atom can facilitate various chemical reactions, such as cross-coupling, while the tert-butyl ester group can be selectively removed under mild conditions to regenerate the free carboxylic acid, making it a valuable intermediate in the synthesis of complex molecules.

217326-47-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 217326-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,3,2 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 217326-47:
(8*2)+(7*1)+(6*7)+(5*3)+(4*2)+(3*6)+(2*4)+(1*7)=121
121 % 10 = 1
So 217326-47-1 is a valid CAS Registry Number.
