About the introduction of L-Penicillamine:

●Description:With the rapid development of science and technology, people's demand for drugs is becoming more and more urgent. In recent decades, the variety of diseases has been increasing, and the emergence of L-penicillamine has brought new eyebrows to the research and development of medical science and technology.
L-penicillamine (C5H11NO2S, L-(+) -penicillamine) is prepared by acylation, resolution and hydrolysis of D-penicillamine. It is a white solid with a melting point of 206 degrees Celsius and is soluble. It is stable at room temperature and pressure and avoids contact with reinforcements. L-penicillamine is toxic and slightly harmful to water. Do not expose undiluted or large quantities of products to groundwater, waterways or sewage systems. Do not discharge materials into the surrounding environment without government permission.
L-penicillamine (cas: 1113-41-3) is a key intermediate of many drugs. It has broad market prospects, such as the synthesis of protease inhibitors against AIDS (je-1520, je-2147). At present, both drugs are in the stage of clinical trials and have good antiviral efficacy. At the same time, they are also the cardiovascular drug sd3321 and the anticancer drug ag3. 340 is an important intermediate.

●Uses:L-Penicillamine is a metabolite of penicillin. L-Penicillamine is used in the treatment of Wilson Holmium Disease, Cystinuria, Scleroderma and arsenic poisoning.

●Storage:keep sealed and keep from direct light
