H-TYR-NH2 HCL Chemical Properties,Usage,Production
Description
L-Tyrosine amide is a tyrosine derivative and chiral ligand that has been used in the in vitro selection of DNA aptamers for the development of aptamer-based biosensors.
Chemical Properties
White to off-white powder
Uses
L-Tyrosinamide is a derivative of Tyrosine, is an amino acid amide[1].
Definition
ChEBI: An amino acid amide that is L-tyrosine in which the carboxy OH group is replaced by NH2.
Synthesis
3417-91-2
4985-46-0
General procedure for the synthesis of (S)-2-amino-3-(4-hydroxyphenyl)propionamide from L-tyrosine methyl ester hydrochloride: L-tyrosine methyl ester hydrochloride (1.16 g, 5 mmol) was added to a 50 mL reaction vessel with concentrated ammonia (40 mL), and the reaction was stirred for 4 hours at room temperature. Upon completion of the reaction, the ammonia was removed by rotary evaporation followed by rotary drying. The crude product was washed with anhydrous ethanol (20 mL x 2) followed by water. Finally, it was purified by column chromatography (silica gel, 200-300 mesh; unfolding agent ratio of ethyl acetate:methanol:ammonia = 300:10:15) to afford L-tyrosine amide in 86% yield.
