Benzo[k]fluoranthene

Benzo[k]fluoranthene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C20H12 and CAS number 207-08-9. This organic compound has a molecular weight of 252.3 g/mol and belongs to the family of fused benzene ring systems. It is classified as a Category 1B carcinogen and poses significant environmental hazards to aquatic life. The substance appears as a crystalline solid and is formed during incomplete combustion of organic materials.

Benzo[k]fluoranthene is a solid crystalline compound at room temperature, typically appearing as yellowish crystals or powder. It has poor water solubility due to its hydrophobic aromatic structure but dissolves in organic solvents such as benzene, toluene, and chloroform. The compound has a high melting point characteristic of PAHs and exhibits stability under normal conditions. Its aromatic structure makes it relatively non-volatile compared to smaller hydrocarbons.

Benzo[k]fluoranthene is primarily used in research and analytical applications as a reference standard for environmental monitoring and toxicological studies. It serves as a marker compound for PAH contamination in environmental samples and is used in laboratory studies investigating carcinogenic mechanisms. Industrial applications are limited due to its hazardous classification, but it may be used in specialized chemical synthesis as an intermediate compound under strictly controlled conditions.

Benzo[k]fluoranthene requires strict safety measures due to its carcinogenic properties. Always wear appropriate personal protective equipment including nitrile gloves, safety goggles, and respiratory protection. Work in a well-ventilated area or fume hood to prevent inhalation exposure. Avoid skin contact and ingestion completely. Use only in designated areas with proper containment measures. All personnel must be trained in carcinogen handling procedures and emergency response protocols before working with this substance.

Benzo[k]fluoranthene must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed in a designated hazardous materials storage area with restricted access. Store away from incompatible materials such as strong oxidizing agents. Maintain storage temperature below 25°C and ensure proper labeling according to GHS requirements. Implement appropriate inventory control and limit quantities to minimize exposure risks.

Benzo[k]fluoranthene exposure requires immediate action due to its carcinogenic nature. For skin contact, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move person to fresh air and seek medical attention. For eye contact, flush with clean water for 15 minutes. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always inform medical personnel about the carcinogenic properties.

Benzo[k]fluoranthene disposal requires specialized hazardous waste management procedures due to its carcinogenic and environmental hazard classification. Contact licensed hazardous waste disposal companies for proper treatment and disposal. High-temperature incineration in approved facilities is typically required. Never dispose of in regular waste streams or pour down drains. Maintain detailed disposal records and follow all local, national, and EU waste regulations including the Waste Framework Directive.

Benzo[k]fluoranthene is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transport purposes. Packages must be properly labeled with appropriate hazard markings and UN numbers. Use approved packaging materials and ensure containers are leak-proof and properly sealed. Transport vehicles must comply with ADR regulations and drivers require appropriate training. Shipping documentation must include proper shipping names, hazard classes, and emergency contact information.

Benzo[k]fluoranthene is subject to extensive European regulations under REACH and CLP frameworks due to its carcinogenic properties and environmental hazards. It requires safety data sheets and hazard communication per GHS standards. The substance may be restricted under various national occupational health regulations and environmental protection laws. Users must comply with worker protection directives and may require special permits or notifications depending on usage quantities and applications.
