657-27-2 Usage


L-Lysine hydrochloride is a white or nearly white, practically odorless, free-flowing, crystalline powder. It is freely soluble in water, but is almost insoluble in alcohol and in ether. It melts at about 260°C with decomposition.


Used in Food and Beverage Industries:
L-Lysine hydrochloride is used as a nutritional supplement for enhancing the protein content and amino acid profile in various food and beverage products.
Used in Animal Feed:
L-Lysine hydrochloride is used as a source of L-Lysine in animal feed, promoting optimal growth and development in livestock.
Used in Pharmaceutical Industry:
L-Lysine hydrochloride is used in the pharmaceutical industry for the production of various medications and supplements, due to its essential role in human nutrition and health.
Used in Agriculture/Animal Feed Industry:
L-Lysine hydrochloride is used in agriculture and animal feed industry to improve the nutritional value of feed, leading to better animal health and productivity.
Used in Other Industries:
L-Lysine hydrochloride can be used in a wide variety of other industries, such as cosmetics, personal care products, and research applications, owing to its versatile properties and benefits.


L-Lysine hydrochloride can be synthesisied by microbial fermentation to give?crude L-Lysine , and then purified and synthesized by crystallization in hydrochloric acid.

Biochem/physiol Actions

L-lysine is an essential amino acid in animals and humans. L-Lysine is necessary for protein synthesis in the body and proper growth. L-lysine lowers the cholesterol level by producing carnitine. L-lysine aids in calcium, zinc and iron absorption. Athletes take L-lysine as a supplement for lean mass building and for proper muscle and bone health. L-lysine competes with arginine during viral replication and reduces herpes simplex virus infection. L-lysine supplementation reduces chronic anxiety in human. Lysine reduces viscosity of serum albumin solution for injections.

Safety Profile

iWdly toxic by ingestion. When heated to decomposition it emits very toxic fumes of HCl and NOx.

Purification Methods

Likely impurities are arginine, D-lysine, 2,6-diaminoheptanedioic acid and glutamic acid. Crystallise the monohydrochloride from water at pH 4-6 by adding 4 volumes of EtOH. At above 60% relative humidity it forms a dihydrate. [Birhbaum et al. J Biol Chem 194 455, 468 1952, Kearley & Ingersoll J Am Chem Soc 73 5783 1951, Beilstein 4 IV 2717.]

Check Digit Verification of cas no

The CAS Registry Mumber 657-27-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 657-27:
82 % 10 = 2
So 657-27-2 is a valid CAS Registry Number.

Chiral Receptors for Lysine Based on Covalently Linked Bis- and Tris-binaphthylphosphoric Acids

Octa-Smolin, Frescilia,Thiele, Maike,Yadav, Rohan,Platzek, André,Clever, Guido H.,Niemeyer, Jochen

supporting information, p. 6153 - 6156 (2018/10/05)

The synthesis and application of three chiral receptors based on the covalent linkage of 1,1′-binaphthylphosphoric acids is reported. The binding of the lysine enantiomers to the chiral receptors was investigated by DOSY-NMR and NMR titrations, revealing that the bisphosphoric acid 1d acts as a highly stereoselective receptor for binding of d-lysine.
