Chemical Description
L-cysteine hydrochloride monohydrate is an amino acid that contains a thiol group and is commonly used in protein synthesis.
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
Different sources of media describe the Uses of 7048-04-6 differently. You can refer to the following data:
1. 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.
2. L-Cysteine hydrochloride monohydrate is used as a precursor in food, pharmaceutical and personal care products. It is actively involved in the production of flavors such as meat flavor obtained by reacting with sugars. It plays an important role as a key raw material for the manufacture of N-acetyl-L-cysteine, S-carboxymethyl-L-cysteine and L-cysteine base. It is involved in the treatment of liver disease as an antioxidant and antidote. Being an essential amino acid, it used as animal feed especially for sheep, which is responsible the growth of wool.
3. L-Cysteine hydrochloride monohydrate has been used as a component of yeast dropout media for culturing yeasts. It has also been used as a component of differential reinforced clostridial broth (DRCM) for the isolation of clostridia.

Check Digit Verification of cas no
The CAS Registry Mumber 7048-04-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,4 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7048-04:
(6*7)+(5*0)+(4*4)+(3*8)+(2*0)+(1*4)=86
86 % 10 = 6
So 7048-04-6 is a valid CAS Registry Number.

Method for optical resolution of DL-cysteine by (1) reacting DL-cysteine with formaldehyde to prepare DL-thiazolidine-4-carboxylic acid (DL-TCA), (2) forming diastereomer salts of D-TCA and of L-TCA by reacting DL-TCA with an optically active 1-(1-naphthyl)ethylamine, (3) separating said diastereomer salts by difference of the solubilities thereof in a solvent, (4) recovering D-TCA from said diastereomer salt of D-TCA and finally obtain D-cysteine, and recovering L-TCA from said diastereomer salt of L-TCA and finally obtain L-cysteine. Method for optical resolution of (R,S)-1-(1-naphthyl)ethylamine (R,S)-NEA by (1) reacting an optically active cysteine with formaldehyde to prepare an optically active thiazolidine-4-carboxylic acid, (2) forming diastereomer salts of (R)-NEA and of (S)-NEA by reacting (R,S)-NEA with optically active thiazolidine-4-carboxylic acid, (3) separating said diastereomer salts of (R)-NEA and of (S)-NEA by difference of the solubilities thereof in a solvent, (4) recovering (R)-NEA from said diastereomer salt of (R)-NEA, and recovering (S)-NEA from said diastereomer salt of (S)-NEA.
