White crystalline powder with garlic like odor and sour taste. Hygroscopic, soluble in water or ethanol, insoluble in ether, chloroform. It is acidic in aqueous solution (pH 2-2.75 in 10g / L H2O), mp101-107 ℃.
This product is an N-acetylated derivative of cysteine, containing sulfhydryl group in the molecule, which can break the disulfide bond (- S-S -) of mucin peptide bond, thus making mucin chain become small molecular peptide chain, reducing the viscosity of mucin. Therefore, this product is a dissolving drug for mucus, purulent sputum and respiratory mucus.
