2-Mercapto-1,3,4-thiadiazole (MTD) is widely used as a corrosion inhibitor in industrial applications, including oil and gas systems, cooling water, metalworking fluids, and cleaners. Its ability to form protective films on metal surfaces helps prevent corrosion in harsh environments such as acidic and sulfur-containing conditions, extending the lifespan of equipment and infrastructure. MTD is also employed as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, where it contributes to the production of biologically active compounds, enhances pesticide efficacy, and inhibits unwanted microbial growth. Additionally, it finds use in the rubber and plastics industries as a vulcanization accelerator and cross-linking agent, enhancing the strength, durability, heat resistance, and flexibility of products. Its versatile properties make it valuable in various chemical processes and material applications.
