129077-96-9 Usage
General Description
L-Tyrosine-beta-13C is a stable isotope of the amino acid L-tyrosine, labeled with the carbon-13 isotope. It is commonly used in biochemical and medical research as a tracer for metabolic studies and for the analysis of metabolic pathways. The labeling with the carbon-13 isotope allows for the tracking and measurement of the metabolism of tyrosine in biological systems, and is particularly useful for studying processes such as protein synthesis and neurotransmitter production. L-Tyrosine-beta-13C is also used in the production of labeled compounds for use in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry.
Check Digit Verification of cas no
The CAS Registry Mumber 129077-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,7 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129077-96:
(8*1)+(7*2)+(6*9)+(5*0)+(4*7)+(3*7)+(2*9)+(1*6)=149
149 % 10 = 9
So 129077-96-9 is a valid CAS Registry Number.

An asymmetric synthesis of L-[3-13C]phenylalanine and L-[3- 13C]tyrosine from [13C]carbon monoxide

L-[3-13C]Phenylalanine and L-[3-13C]tyrosine were synthesized. [α- 13C]Benzyl bromides were prepared from [13C]carbon monoxide via the palladium-catalyzed carboalkoxylation of aryl halides. The asymmetric carbon corresponding to the 2-position in phenylalanine was introduced by the diastereoselective alkylation of Dellaria's oxazinone with [α-13C]benzyl bromides. Finally, ethanolysis, deprotection, hydrogenolysis and acid hydrolysis of the resulting alkylated oxazinones gave L-[3- 13C]phenylalanine and L-[3-13C]tyrosine in high optical purity.
