Key Properties
Sodium thioglycolate (for bacteriology, thioglycolic acid sodium salt) is a vital reducing agent used primarily in anaerobic bacterial culture media. This compound is recognized for its ability to create a low-oxygen environment, which is essential for the growth of anaerobic and microaerophilic bacteria. With a molecular weight of 114.10 g/mol and a CAS number of 367-51-1, sodium thioglycolate is a key component in microbiological laboratories. Its effectiveness in promoting bacterial growth under anaerobic conditions makes it indispensable in bacteriology and related fields.
Also known as Thioglycolic acid sodium salt.
