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 ring aromatic compounds. 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 primarily found as a byproduct of incomplete combustion processes.

Benzo[k]fluoranthene is a solid crystalline compound at room temperature, typically appearing as pale yellow to light brown crystals or powder. It has limited water solubility due to its hydrophobic aromatic structure but dissolves well in organic solvents such as benzene, toluene, and chloroform. The compound exhibits low volatility and high thermal stability. Its aromatic nature gives it characteristic UV absorption properties, making it detectable through spectroscopic methods.

Benzo[k]fluoranthene is primarily used as a research chemical and analytical standard in environmental monitoring laboratories. It serves as a reference material for PAH analysis in soil, water, and air samples. The compound is also utilized in toxicological studies and carcinogenicity research. Due to its hazardous properties, it has limited industrial applications and is mainly handled in controlled laboratory environments for scientific research purposes and regulatory compliance testing.

Benzo[k]fluoranthene requires strict safety precautions due to its carcinogenic properties. Always wear appropriate personal protective equipment including nitrile gloves, safety goggles, and lab coats. Work in a well-ventilated area or under a fume hood to prevent inhalation exposure. Avoid skin contact and ingestion completely. Use proper laboratory techniques to minimize dust generation and potential exposure. Ensure all personnel are trained in handling carcinogenic substances and follow established safety protocols.

Benzo[k]fluoranthene should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep containers in a designated area for carcinogenic substances with restricted access. Store away from strong oxidizing agents and incompatible materials. Maintain storage temperature below 25°C and ensure containers are properly labeled with hazard warnings. Regular inventory checks and proper documentation of storage conditions are essential for compliance.

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

Benzo[k]fluoranthene disposal must comply with local and international hazardous waste regulations due to its carcinogenic and environmentally hazardous properties. Never dispose of this substance in regular waste streams or pour down drains. Contact licensed hazardous waste disposal companies for proper treatment, which typically involves high-temperature incineration in specialized facilities. Maintain detailed disposal records and ensure all containers are properly labeled before collection. Follow your local regulatory requirements for hazardous waste management.

Benzo[k]fluoranthene is classified as ADR Class 9 (miscellaneous dangerous goods), Packing Group III for transportation purposes. It must be packaged in appropriate containers that meet UN specification requirements and properly labeled with hazard markings. Transport documents must include the correct shipping name and hazard classifications. Vehicles must carry appropriate emergency equipment and drivers should be trained in handling hazardous materials. Ensure compliance with international transport regulations for dangerous goods.

Benzo[k]fluoranthene is subject to extensive regulatory oversight under European REACH regulation due to its carcinogenic properties and environmental hazards. It falls under CLP classification as Carcinogen 1B and requires appropriate hazard labeling with GHS08 and GHS09 pictograms. The substance is regulated in workplace exposure limits and environmental monitoring programs. Special authorization may be required for certain uses, and strict reporting obligations apply to manufacturers and importers under chemical safety legislation.
