2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile is a chlorinated aromatic compound with the molecular formula C8Cl4N2 and CAS number 1897-45-6. This chemical features a benzene ring substituted with four chlorine atoms and two nitrile groups, giving it a molecular weight of 265.9 g/mol. It is classified as a hazardous substance with multiple danger classifications including potential carcinogenicity, acute toxicity, and environmental hazards.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile is a solid crystalline compound at room temperature due to its chlorinated aromatic structure. The presence of four chlorine atoms and two nitrile groups significantly affects its physical properties, making it relatively stable but poorly soluble in water. Its molecular structure with multiple electron-withdrawing groups contributes to its chemical stability and low volatility under normal conditions.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. Its unique structure with both chlorine substituents and nitrile groups makes it valuable for producing specialized compounds in the chemical industry. Due to its hazardous classification, its use is typically restricted to professional industrial applications under controlled conditions with appropriate safety measures.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile requires strict safety protocols due to its acute toxicity and potential carcinogenic properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Skin and eye contact must be avoided at all costs, and emergency washing facilities should be readily accessible during handling operations.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. The substance should be kept in tightly sealed, chemically compatible containers to prevent contamination and exposure. Storage areas should be equipped with appropriate containment measures and restricted to authorized personnel only, with clear hazard labeling and emergency procedures readily available.

Immediate medical attention is required for any exposure to 2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile due to its acute toxicity classification. For skin contact, remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse immediately with water and seek urgent medical care. If inhaled, move the person to fresh air immediately and contact emergency medical services.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile must be disposed of as hazardous waste through licensed waste management companies in accordance with local and European regulations. The substance cannot be disposed of in regular waste streams due to its toxic and potentially carcinogenic properties. Disposal methods typically include high-temperature incineration at specialized facilities equipped to handle chlorinated organic compounds while preventing environmental contamination.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile is classified under ADR Class 6.1 (Toxic substances) Packing Group II, indicating significant transport restrictions. Transportation requires specialized packaging, proper hazard labeling, and documentation in accordance with dangerous goods regulations. Only authorized carriers with appropriate certifications can transport this substance, and emergency response information must accompany shipments to ensure proper handling in case of incidents.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile is subject to comprehensive European chemical regulations including REACH registration and CLP classification requirements. Its multiple hazard classifications require strict compliance with occupational safety standards, environmental protection measures, and transport regulations. While not currently listed as a SVHC, its carcinogenic potential and environmental hazards mean it faces stringent use restrictions and reporting obligations across European markets.

2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile is available through OYSI, a specialized European distributor of technical chemicals and intermediates. As a professional chemical supplier, OYSI ensures compliance with all regulatory requirements and provides proper documentation, safety data sheets, and technical support. Due to the hazardous nature of this substance, purchases are typically restricted to qualified industrial users with appropriate handling capabilities and regulatory compliance.
