Dimethylthiocarbamoyl Chloride (CAS 16420-13-6) is a chemical compound that demands careful attention regarding its properties, handling, and sourcing. This article provides a comprehensive overview for professionals in the chemical industry, focusing on its physical characteristics, essential safety precautions, and best practices for procurement, especially when looking to buy Dimethylthiocarbamoyl Chloride from reliable sources.

Physical and Chemical Properties

Dimethylthiocarbamoyl Chloride, with the chemical formula C3H6ClNS and a molecular weight of approximately 123.60 g/mol, is typically described as a white to pale yellow crystalline solid or crystals. Its physical state is influenced by its relatively low melting point, ranging from 39-43°C. The compound exhibits a boiling point of 90-95°C at 0.5 mm Hg, indicating its volatility under reduced pressure. It is soluble in common organic solvents like chloroform and tetrahydrofuran. A critical property to note is its sensitivity to moisture, which can lead to hydrolysis, and its corrosive nature.

Safety and Handling Precautions

Due to its corrosive and moisture-sensitive nature, proper handling of Dimethylthiocarbamoyl Chloride is paramount. Safety data sheets (SDS) typically indicate hazard codes such as H302 (Harmful if swallowed), H314 (Causes severe skin burns and eye damage), and H317 (May cause an allergic skin reaction). Recommended safety measures include:

  • Personal Protective Equipment (PPE): Always wear appropriate gloves, eye protection (goggles or face shield), and protective clothing.
  • Ventilation: Handle in a well-ventilated area or fume hood to avoid inhalation of vapors, which can be irritating.
  • Moisture Exclusion: Store and handle under anhydrous conditions to prevent degradation and maintain product integrity.
  • Storage: Keep containers tightly closed in a cool, dry place, away from incompatible materials. Recommended storage temperatures are often 2-8°C.

Procurement Strategies for Dimethylthiocarbamoyl Chloride

When seeking to purchase Dimethylthiocarbamoyl Chloride, buyers often look for a balance of quality, reliability, and competitive price. China is a significant source for this chemical intermediate. Key considerations for procurement include:

  • Supplier Verification: Identify reputable manufacturers and suppliers with established quality control systems.
  • Product Specifications: Ensure the purity (commonly 98%) and physical form meet your application requirements.
  • Documentation: Request Certificates of Analysis (CoA) and SDS to confirm product quality and safety information.
  • Packaging and Delivery: Understand the packaging options (e.g., aluminum foil bags, drums) and inquire about shipping logistics.

Negotiating the Dimethylthiocarbamoyl Chloride price for bulk orders is a common practice. Working with a transparent supplier who provides responsive customer service and technical support is beneficial for a smooth procurement process.

In summary, Dimethylthiocarbamoyl Chloride is a critical but hazardous chemical. Adhering to strict safety protocols and engaging with trustworthy suppliers are essential steps for any organization needing to procure this important chemical intermediate.
