Used primarily in the textile industry as a fixing agent for dyes, it enhances color fastness and improves the durability of dyed fabrics. It also serves as a crosslinking agent in polymer chemistry, aiding in the formation of stable networks within resins and coatings. In water treatment, it acts as a biocide, effectively controlling microbial growth. Additionally, it finds application in the synthesis of organic compounds, particularly in the production of pharmaceuticals and agrochemicals, where it acts as an intermediate or stabilizer. Its ability to react with proteins makes it useful in biochemical research for modifying or studying protein structures.
