L-色胺酸乙酯盐酸盐 - Reference Information
| Introduction | L-tyrosine is one of the 20 amino acids that make up proteins and is an essential amino acid for mammals. L-tyrosine ethyl ester hydrochloride is the main raw material for the synthesis of a variety of peptide hormones, antibiotics and other drugs. |
| use | L-tyrosine ethyl ester hydrochloride is the main raw material for synthesizing a variety of peptide hormones, antibiotics and other drugs. In the food industry, L-tyrosine ethyl ester hydrochloride is used instead of amino acids as food additives, which can change the taste and flavor of food and increase the shelf life of food. Amino acid esters used in food also increase the solubility of amino acids and the specificity of enzyme catalysis, which is beneficial to the digestion and absorption of the body and plays a dual role in nutrition and health care. |
| preparation method | add 19 mL of anhydrous ethanol into a 250 mL three-mouth flask equipped with a stirrer, a dropping funnel and a thermometer, cool it to about -8 ℃ in an ice salt bath for external use, slowly add 2.4 mL of sulfoxide chloride under stirring (the dropping acceleration is limited to the reaction temperature not exceeding 0 ℃), after dropping, stir at this temperature for 1 h, add 4.5g L-tyrosine under cooling conditions, raise the temperature to room temperature and stir for 2 h, then heat and reflux at 65 ℃ for 2 h, distill after the reaction to evaporate most methanol and excess thionyl chloride, transfer the residue to a beaker for cooling, add 125 mL ethyl acetate to precipitate a large amount of crystals, vacuum filtration, and collect crystals, L-tyrosine ethyl ester hydrochloride was obtained. |
