Uses

N-Pivaloyl-L-tyrosine can be used in peptide N-terminal amino acid determination.

Preparation

Preparation of N-Pivaloyl-L-tyrosine Ethyl EsterN-Pivaloyl-L-tyrosine could not be prepared from L-tyrosine following the previous method. Under the same conditions used for the preparation of IK, 90% of the starting material remained unreacted. N-Pivaloyl-L-tyrosine Ethyl Ester was, however, made from Ie by mild hydrolysis with dilute sodium hydroxide solution and subsequent esterification with absolute ethyl alcohol saturated with dry HCl gas. The material after chromatography on florisil was obtained as an oil. Comparison of the mobility with Ie on thin-layer chromatography in two solvent systems (I and 11) as well as conversion to Ie by further acylation confirmed the identity of the material.

Check Digit Verification of cas no

The CAS Registry Mumber 33019-85-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,1 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33019-85:
(7*3)+(6*3)+(5*0)+(4*1)+(3*9)+(2*8)+(1*5)=91
91 % 10 = 1
So 33019-85-1 is a valid CAS Registry Number.
