Carbocysteine Powder Usage and Synthesis.

Carbocysteine is used in biochemical studies as a mucolytic agent.S-Carboxymethyl-L-Cysteine is mainly used in the treatment of chronic bronchitis, bronchial asthma and other diseases caused by thick sputum, difficult to cough up sputum and sputum obstruction of the trachea, Carbocysteine Powder is a mucolytic agent, expectorant, anti-nasal infection. Carbocysteine Powder is a mucolytic, expectorant and anti-nasal infection.

Uses and functions of Carbocysteine Powder.

S-Carboxymethyl-L-cysteine/ Carbocisteine is a respiratory mucolytic agent. Its action is similar to that of bromhexine in that it causes the disulfide bond of mucin in sputum to be cleaved, thereby reducing the viscosity of sputum and increasing the mucus fibres in sputum, lubricating the bronchial lining, increasing the secretion of low viscosity salivary mucin and reducing the production of high viscosity rockweed mucin, thereby reducing the viscosity of sputum and making it easier to cough up.

Pharmacological Effects of Carbocysteine Powder.

S-Carboxymethyl-L-Cysteine is white crystalline powder; odorless, acidic

S-Carboxymethyl-L-Cysteine for Biochemical Research

Production method of Carbocysteine Powder.

L-cysteine was prepared as an aqueous solution of disodium salt, reacted with chloroacetic acid in the presence of sodium metabisulfite, firstly reacted at 20-30°C for 0.5h, then reacted at 20°C for 15min, activated carbon was added to the reactants, filtered, and the filtrate was acidified with concentrated hydrochloric acid to pH2.5, which resulted in the formation of carboxymethylstannane precipitate, filtered, washed and vacuum dried, which resulted in the finished product. In terms of L-cysteine, the yield is 92%.
