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 highly chlorinated aromatic compound has a molecular weight of 284.8 g/mol and consists of a benzene ring with six chlorine atoms attached to each carbon position. It is classified as a hazardous substance with carcinogenic properties and potential for bioaccumulation in the environment.

1,2,3,4,5,6-hexachlorobenzene is a white crystalline solid at room temperature with high thermal stability due to its fully chlorinated structure. It has low water solubility but is soluble in organic solvents such as benzene, chloroform, and oils. The compound is odorless and exhibits high persistence in the environment due to its resistance to degradation processes.

1,2,3,4,5,6-hexachlorobenzene is primarily used as an intermediate in chemical synthesis and as a specialized industrial chemical. It serves in the production of other chlorinated compounds and can be used in research applications. Due to its hazardous properties and environmental persistence, its commercial applications are highly restricted and regulated in most jurisdictions, with many historical uses being discontinued.

1,2,3,4,5,6-hexachlorobenzene requires strict safety protocols due to its carcinogenic classification (Carc. 1B). Workers must wear appropriate personal protective equipment including chemical-resistant gloves, protective clothing, and respiratory protection. Handle only in well-ventilated areas or under fume extraction systems. Avoid skin contact, inhalation, and ingestion. Emergency shower and eyewash facilities should be readily accessible in work areas.

1,2,3,4,5,6-hexachlorobenzene must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Keep containers away from heat sources, direct sunlight, and ignition sources. Store in dedicated chemical storage areas with appropriate containment measures to prevent environmental release. Ensure storage areas are equipped with spill control measures and comply with local hazardous material storage regulations.

Immediate action is required upon contact with 1,2,3,4,5,6-hexachlorobenzene. For skin contact, remove contaminated clothing and wash 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 and provide the safety data sheet to medical personnel.

1,2,3,4,5,6-hexachlorobenzene disposal requires specialized hazardous waste management due to its persistent organic pollutant characteristics. The substance must be disposed of through licensed hazardous waste contractors capable of handling organochlorine compounds. High-temperature incineration in authorized facilities is typically required. Never dispose of through regular waste streams, sewers, or soil. Consult local environmental authorities for specific disposal requirements and approved facilities.

1,2,3,4,5,6-hexachlorobenzene is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. It requires appropriate UN specification packaging and hazard labels during transport. Shipping documents must include proper shipping names, hazard classifications, and emergency response information. Transport vehicles should carry appropriate emergency equipment and drivers must be trained in hazardous material handling procedures according to ADR regulations.

1,2,3,4,5,6-hexachlorobenzene is subject to extensive regulation under REACH, CLP, and Stockholm Convention on Persistent Organic Pollutants. It requires registration for commercial use and is classified with specific hazard statements under CLP regulation. The substance may be subject to authorization requirements and use restrictions. Companies must comply with safety data sheet provisions, exposure scenario requirements, and downstream user obligations under European chemical 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 regulatory status and hazardous classification, procurement requires compliance with REACH obligations and proper authorization for intended uses. OYSI can provide technical support, safety documentation, and regulatory guidance for qualified industrial customers requiring this specialized chemical compound.
