N-Acetyl-L-cysteine CAS 616-91-1

High quality N-Acetyl-L-cysteine CAS 616-91-1 is offered by China manufacturer Believe Chemical. N-Acetyl-L-cysteine CAS 616-91-1 Biological reagent, bulk drug, sulfhydryl (-sh) contained in the molecule can break the disulfide chain (-s-s) connecting the mucin peptide chain in mucus sputum. Mucin turns into a peptide chain of small molecules of chemicalbook, reducing the viscosity of sputum; It can also break the DNA fibers in purulent sputum, so it can dissolve not only white sticky sputum but also purulent sputum.

Production method

Dissolve L-cysteine hydrochloride (without crystal water) in 0.8 times distilled water, and then heat it appropriately. Then filter it in a funnel with activated carbon. Add 3.6 times the volume of 95% medicinal ethanol to the filtrate, and then add industrial pyridine (0.8 times the volume of chemical book). 

First cool it in an ice water bath, and then put it into the refrigerator overnight. The next day, filter it, wash it with chloroform (industrial product), filter it, press it dry, quickly put it into a vacuum dryer, and dry it at room temperature for 5h to get L-cysteine. The yield was 86.5%.
