Methylene Dithiocyanate (MBT), identified by its CAS number 6317-18-6, is a potent chemical compound utilized across various industries primarily for its biocidal and fungicidal properties. For professionals involved in procurement, formulation, or application, a thorough understanding of its chemical properties, safe handling procedures, and specifications is crucial for optimal and secure utilization.

Chemically, MBT is known as Methylene bis(thiocyanate) and has the molecular formula C3H2N2S2. It typically appears as a white to light yellow or light orange crystalline powder. Its melting point generally falls within the range of 101-106°C, indicating its solid state at room temperature. While slightly soluble in organic solvents like methanol, it decomposes in water, making its handling and storage conditions important considerations. Its stability is generally good, but it is noted to be moisture-sensitive and can react vigorously with strong bases and oxidizing agents.

From a safety perspective, MBT is classified as a hazardous substance. Sources indicate it can cause severe skin burns and eye damage, may trigger allergic skin reactions, and is toxic if inhaled or swallowed. Therefore, strict adherence to safety protocols is paramount when handling this chemical. This includes wearing appropriate personal protective equipment (PPE) such as gloves, eye protection, and respiratory protection, especially when dealing with dust or aerosols. Proper ventilation in work areas is also essential. Manufacturers and suppliers typically provide comprehensive Safety Data Sheets (SDS) that detail hazards, first-aid measures, and recommended handling procedures. Procurement teams should always ensure they have access to and understand these critical documents.

Key specifications that buyers often look for include assay (purity), moisture content, and acetone insolubility. An assay of ≥98% is commonly sought after for industrial applications to ensure consistent performance. Moisture content should be kept low, typically ≤0.5% or ≤1.0%, to maintain product stability. Acetone insolubles should also be minimal, usually ≤1.0%, indicating a cleaner product. Understanding these specifications allows buyers to compare different suppliers and make informed decisions about product quality.

For those looking to source MBT, partnering with reputable chemical manufacturers and suppliers is essential. They can provide not only the required product specifications but also crucial safety information and application guidance. Whether you are looking to buy MBT for water treatment, agriculture, or material preservation, ensuring you obtain it from a trusted source that prioritizes quality and safety will lead to successful and responsible use of this valuable chemical.
