Sodium thioglycolate Application scenarios
1. Core Component of Microbial Culture Media:
As a reducing agent and antibacterial agent in anaerobic culture media, it maintains a low-oxygen environment, inhibits aerobic bacteria, and promotes the growth of anaerobic bacteria such as Clostridium and Salmonella. It is used for the enrichment, isolation, and identification of anaerobic bacteria in clinical specimens, food, and environmental samples. Common addition concentrations are 0.05%-0.5% (w/v). It can also protect the sulfhydryl groups of enzymes from oxidation, and is used in microbiology and inflammation-related research.
2. Mining Flotation Inhibitor:
In copper-molybdenum ore flotation, it selectively inhibits minerals such as copper sulfide and pyrite, improving the grade of molybdenum concentrate. It is an environmentally friendly, cyanide-free flotation inhibitor that can replace highly toxic sodium cyanide, reducing environmental risks.
3. Daily Chemical Hair Care and Hair Removal Products:
Used in cold perm/straightening agents, it breaks the disulfide bonds in hair keratin to shape and maintain the curl effect; as a main ingredient in hair removal creams, it breaks the disulfide bonds in hair, making it easier to remove; it can also be used as an antioxidant and reducing agent in cosmetics.
4. Analytical Chemistry Reagent:
Used for the determination and masking of metal ions such as iron, molybdenum, silver, and tin, such as complexing metal ions to eliminate interference. Also used in iron tests and sample processing for protein analysis.
5. Pharmaceuticals and Biopharmaceuticals:
As a stabilizer in pharmaceutical formulations, protecting the thiol groups of active ingredients; used in topical dermatological formulations to help improve skin problems; also used as a pharmaceutical intermediate in the synthesis of specific drugs.
6. Textile Printing and Dyeing Auxiliaries:
Used as a transfer agent and fixing agent in fabric printing, promoting dye fixation, improving print clarity and color fastness; also used in the reduction and cleaning of textiles.
7. Other Industrial Uses:
In photography, it can be used as a reducing agent in film development; in polymer synthesis, it is used as a chain transfer agent or stabilizer; it can also be used in metal surface treatment, such as corrosion inhibition and cleaning.
