In the intricate world of chemical compounds, MBT, also known as 2-Benzothiazolethiol, stands as a crucial component primarily utilized as a corrosion inhibitor. While it plays a vital role in preventing the corrosion of copper and copper-containing metals, it is essential to delve into the various aspects of MBT, from its chemical composition to potential health risks associated with exposure. In this blog post, we unravel the characteristics of MBT, its uses, health implications, and considerations for measurement.
Chemical Composition and Other Names:
MBT is identified by various names, including 2-Benzothiazolethiol. Its chemical formula is C7H5NS2 or C6H4NSCSH, reflecting its molecular structure. The CAS number assigned to MBT is 149-30-4. This compound finds application as a corrosion inhibitor, showcasing its versatility in industrial settings.
Industry Uses:
The primary use of MBT lies in its role as a corrosion inhibitor. It is formulated into various water treatment products specifically designed to prevent the corrosion of copper and copper-containing metals. This makes MBT particularly valuable in closed-loop cooling water systems and utility condensers, where maintaining high MBT concentrations is common practice.
Health Risks and Exposure:
While MBT serves a crucial purpose in corrosion prevention, its exposure comes with potential health risks. MBT is known to be a chemical allergen, triggering increased histamine release and cell-mediated immunity, leading to skin reactions and contact dermatitis. It is highly irritating to the eyes and skin, posing risks for individuals who come into direct contact with it.
Furthermore, MBT is categorized as a probable carcinogen, indicating a potential link to the development of cancer. The chemical is considered harmful through various routes, including inhalation, ingestion, and absorption. When subjected to decomposition through heating, MBT emits fumes that are highly toxic, adding an additional layer of concern for occupational safety.
Regulations:
As of now, there are no specific regulations or restrictions stipulated for the levels of MBT in water. This lack of regulatory guidance emphasizes the need for vigilance and responsible handling of MBT in industrial processes to minimize potential health and environmental impacts.

Accurate measurement of dissolved MBT concentration in water is crucial for monitoring and ensuring adherence to safety standards. CHEMetrics offers a specialized kit for determining MBT levels in water, ranging from 50-500 ppm. This kit provides a reliable method for assessing the presence of MBT, allowing industries to manage and mitigate potential risks associated with its use.
MBT plays a vital role in corrosion inhibition, contributing to the longevity and efficiency of industrial equipment. However, its health implications underscore the importance of responsible handling and monitoring. As industries continue to rely on MBT for corrosion prevention, a balanced approach that considers both industrial efficacy and safety is essential. Rigorous measurement, adherence to safety protocols, and ongoing awareness of potential health risks are critical in ensuring the responsible use of MBT in various industrial applications.
