L-Cysteine hydrochloride monohydrate Chemical Properties,Uses,Production

Application

L-cysteine ​​hydrochloride monohydrate has been used in protocols to isolate dorsal root ganglion neurons (DRG).  It was also used in research to test its effect as an inhibitor of enzymatic browning of apples.

General descriptio

L-cysteine ​​hydrochloride monohydrate (LCHCMH) is a water-soluble salt of the non-essential amino acid L-cysteine. It is widely used in the pharmaceutical industry. The thermodynamic characteristics of LCHCMH in aqueous solution have been reported. [1] It can be crystallized in an orthogonal system with the P212121 space group. Its nonlinear optical (NLO) characteristics have been studied in single crystals grown by unidirectional Sankaranarayanan-Ramasamy (SR) technology.

Chemical Properties

white crystalline powder

Uses

L-Cysteine is a non-essential amino acid that can be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available. L-Cysteine is commonly use d as a precursor in the food and pharmaceutical industries. L-Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours.

Definition

ChEBI: A hydrate that is the monohydrate form of L-cysteine hydrochloride.

Purification Methods

Likely impurities are cystine and tyrosine. Crystallise the salt from MeOH by adding diethyl ether, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]
