1,2,3,4,5,6-hexachlorobenzene

1,2,3,4,5,6-hexachlorobenzene is a synthetic organochlorine compound with the molecular formula C6Cl6 and CAS number 118-74-1. This substance consists of a benzene ring where all six hydrogen atoms have been replaced by chlorine atoms, resulting in a highly chlorinated aromatic compound with a molecular weight of 284.8 g/mol. It is classified as a hazardous substance with carcinogenic properties and environmental toxicity concerns.

1,2,3,4,5,6-hexachlorobenzene is a white crystalline solid at room temperature with very low water solubility due to its highly chlorinated structure. The compound exhibits high chemical stability and persistence in the environment. It has low volatility and tends to bioaccumulate in fatty tissues. The substance is lipophilic, making it soluble in organic solvents and fats but practically insoluble in water.

1,2,3,4,5,6-hexachlorobenzene is primarily used as an intermediate in chemical synthesis and research applications. Historically, it was used in the production of other chlorinated compounds and as a fungicide, though many uses have been restricted due to environmental and health concerns. Currently, its applications are mainly limited to specialized industrial processes and analytical chemistry as a reference standard or research chemical.

Safe handling of 1,2,3,4,5,6-hexachlorobenzene requires comprehensive personal protective equipment including chemical-resistant gloves, protective clothing, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Given its carcinogenic classification (Carc. 1B), minimize skin contact and avoid dust generation. Implement strict hygiene measures, including thorough handwashing and contaminated clothing removal before leaving work areas.

1,2,3,4,5,6-hexachlorobenzene should be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly closed and properly labeled in a secure chemical storage area with restricted access. Store separately from oxidizing agents, strong bases, and food products. Ensure storage areas have appropriate spill containment measures and maintain inventory records due to the substance's hazardous classification.

In case of skin contact with 1,2,3,4,5,6-hexachlorobenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately. For eye contact, rinse with clean water for at least 15 minutes. Seek immediate medical attention in all cases of exposure, informing healthcare providers of the substance identity and providing the safety data sheet.

Disposal of 1,2,3,4,5,6-hexachlorobenzene must be conducted through licensed hazardous waste disposal facilities due to its environmental persistence and toxicity. The substance requires high-temperature incineration under controlled conditions to ensure complete destruction. Never dispose of this material in regular waste streams, sewers, or the environment. Consult local environmental regulations and use certified waste disposal contractors specialized in handling persistent organic pollutants.

Transportation of 1,2,3,4,5,6-hexachlorobenzene is regulated under ADR classification 6.1 (toxic substances), packing group III. The substance must be packaged in UN-approved containers with proper hazardous material labels and documentation. Transport vehicles require appropriate placarding and drivers need hazmat certification. Shipping documentation must include proper shipping names, hazard classes, and emergency contact information for regulatory compliance.

1,2,3,4,5,6-hexachlorobenzene is subject to strict regulations under REACH, CLP, and various international conventions including the Stockholm Convention on Persistent Organic Pollutants. Its carcinogenic classification requires special handling procedures and exposure monitoring. The substance may face import/export restrictions and requires detailed safety data sheets. Users must comply with occupational exposure limits and environmental protection measures as mandated by European and national legislation.

1,2,3,4,5,6-hexachlorobenzene is available through specialized chemical distributors like OYSI, which serves the European market with technical-grade chemicals. Due to its hazardous classification and regulatory restrictions, procurement requires proper documentation, end-use declarations, and compliance with safety regulations. OYSI provides technical support and ensures proper packaging and documentation for safe delivery to qualified industrial and research customers across Europe.
