In the global chemical supply chain, Hazard Class 9 (Miscellaneous Dangerous Goods) encompasses substances that present potential risks but do not fit neatly into the first eight hazard classes. These materials require proper handling, storage, and documentation to ensure safety, and two widely used compounds in this category are thiourea and urea—both featured in industrial product listings for their specific properties and applications.
Hazard Class 9 classification serves as a critical marker for businesses and workers, indicating that while these substances are not classified as explosives, corrosives, or acute toxins, they still pose hazards such as environmental risks or potential reactivity under certain conditions. Adherence to safety guidelines and regulatory standards is essential for anyone working with or sourcing these chemicals.
The first compound highlighted is thiourea (CAS No.: 62-56-6), with a molecular formula of CH4N2S. This industrial-grade thiourea boasts a high purity level of 99%, along with a urea nitrogen content of 46% and a specified weight of 9.5kg per unit. Sourced from China, it is valued for its versatility in sectors such as pharmaceuticals, agriculture, and chemical manufacturing. Thiourea is commonly used as a reagent in organic synthesis, a vulcanization accelerator in rubber production, and a metal complexing agent, among other applications. Its high purity ensures consistency and reliability in specialized processes where precision is paramount.
The second compound is urea (CAS No.: 57-13-6), identified by its molecular formula CH4N2O (or CO(NH2)2). With a purity of 46%—a standard specification for industrial and agricultural urea—this compound is one of the most widely produced chemicals globally. Urea’s primary use is as a nitrogen-rich fertilizer, supporting plant growth in agriculture, but it also finds applications in plastics manufacturing, animal feed additives, and as a raw material in the production of resins and adhesives. Its inclusion in Hazard Class 9 stems from its potential to cause irritation and environmental impacts if not handled properly.
Both thiourea and urea share the Hazard Class 9 designation but serve distinct industrial purposes, driven by their unique chemical properties. For businesses sourcing these compounds, verifying key specifications such as CAS number, molecular formula, purity, and weight is crucial to ensure alignment with operational needs and regulatory compliance. Reputable chemical suppliers provide detailed product listings for Hazard Class 9 chemicals like thiourea and urea, offering transparency into origin (e.g., “Made in China” for the thiourea featured) and technical details.
Safety remains a top priority when working with Hazard Class 9 substances. Proper storage in well-ventilated areas, use of personal protective equipment (PPE), and adherence to material safety data sheet (MSDS) guidelines help mitigate risks. Additionally, compliance with international transportation and handling regulations ensures that these chemicals are moved safely across supply chains.
In summary, thiourea and urea are prominent examples of Hazard Class 9 substances, each offering unique value in industrial, agricultural, and manufacturing sectors. Their defined specifications—including high purity levels and clear chemical identifiers—make them reliable choices for businesses seeking consistent, compliant materials. For those in need of these compounds, trusted suppliers provide comprehensive product information to support informed purchasing decisions while upholding safety and regulatory standards.
