Function:
1.Complexing agent function, sodium thioglycolate is an effective complexing agent.
2.Pharmaceutical excipient function, sodium thioglycolate can be used in the production of drugs.
3.Medical testing function, sodium thioglycolate can be used as a reagent for testing certain metal ions.
4. Masking agent function, sodium thioglycolate can be used as masking agent for the determination of certain metal ions in analytical chemistry.
5. Microbial culture function, in microbiology research and microbial industrial production, sodium thioglycolate can be used for anaerobic bacteria culture.
Application:
1. In silver plating, gold plating and other plating solution, it can combine with silver ions, gold ions and so on, control the deposition speed and deposition mode of metal ions, improve the brightness and adhesion of plating layer and so on, so as to improve the quality of plating products.
2. In some pharmaceutical preparations, it can be used as an antioxidant to prevent the drug components from being oxidized and losing their efficacy.
3. It can also be used as stabilizer to stabilize the chemical structure of drugs. For example, in some preparations such as injections or eye drops containing easily oxidized active ingredients.
4.. In medical testing, it can react specifically with heavy metal ions such as mercury ions, and is used in the detection of heavy metal poisoning and so on.
5. Sodium thioglycolate can selectively combine with interfering metal ions to form a stable complex, thus masking the interfering ions and making the determination of target metal ions more accurate.
6. Sodium thioglycolate can make the bottom of the medium form an anaerobic environment, while the upper part is an aerobic environment, so that aerobic and anaerobic bacteria can be cultivated at the same time, which is convenient for the classification and research of microorganisms.
