Benzo[e]pyrene

Benzo[e]pyrene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C20H12 and CAS number 192-97-2. This organic compound consists of five fused benzene rings and has a molecular weight of 252.3 g/mol. It is classified as a carcinogenic substance (Carc. 1B) and poses significant environmental hazards to aquatic life. Benzo[e]pyrene is typically found as a byproduct of incomplete combustion processes and is considered a persistent organic pollutant due to its stability and potential for bioaccumulation.

Benzo[e]pyrene is a solid crystalline compound at room temperature, typically appearing as pale yellow crystals or powder. It has very low water solubility due to its hydrophobic aromatic structure, but dissolves readily in organic solvents such as benzene, toluene, and chloroform. The compound exhibits high thermal stability and has a high melting point characteristic of PAHs. Its low volatility means it tends to remain in solid form under normal conditions, though it can sublime at elevated temperatures.

Benzo[e]pyrene is primarily used in analytical and research applications rather than commercial production. It serves as a reference standard in environmental monitoring and analytical chemistry for detecting PAH contamination in soil, water, and air samples. Research institutions utilize it for toxicological studies and carcinogenicity research. Due to its hazardous classification, industrial applications are extremely limited and heavily regulated. It may also be used in specialized chemical synthesis as an intermediate, though such uses require strict safety protocols and regulatory compliance.

Benzo[e]pyrene requires strict safety protocols due to its carcinogenic properties (Carc. 1B classification). Personnel must wear appropriate PPE including nitrile gloves, safety goggles, and respiratory protection when handling. Work should be conducted in well-ventilated areas or fume hoods to prevent inhalation exposure. Avoid skin contact and ingestion at all costs. Use non-sparking tools and equipment. Ensure emergency eyewash and shower facilities are readily accessible. All personnel should receive proper training on carcinogen handling procedures before working with this substance.

Benzo[e]pyrene must be stored in tightly sealed, chemically compatible containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage areas should be designated for carcinogenic substances with restricted access and appropriate warning signage. Keep away from strong oxidizing agents and incompatible materials. Maintain storage temperature below 25°C to prevent degradation. Containers should be clearly labeled with hazard information and stored in secondary containment to prevent environmental release. Regular inventory checks and proper documentation are essential for regulatory compliance.

Benzo[e]pyrene 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. In case of eye contact, flush with clean water for 15 minutes while holding eyelids open. If inhaled, move person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. In all cases, contact emergency medical services and provide the safety data sheet to medical personnel for proper treatment guidance.

Benzo[e]pyrene disposal must comply with local and international hazardous waste regulations due to its carcinogenic and environmental hazard classifications. The substance cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment facilities. Incineration at high temperatures (>1000°C) with proper emission controls is typically the preferred disposal method. All disposal activities must be documented and performed by licensed waste management companies. Contact local environmental authorities for specific disposal requirements and approved waste treatment facilities in your region.

Benzo[e]pyrene is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. Packages must be properly labeled with appropriate hazard labels including GHS08 and GHS09 pictograms and 'Danger' signal word. Use UN-approved packaging suitable for Class 9 substances. Transport documents must include proper shipping name, UN number, and hazard class information. Vehicles must carry appropriate emergency equipment and drivers require ADR certification. Ensure compliance with international transport regulations including IMDG for sea transport and IATA for air transport.

Benzo[e]pyrene is subject to extensive regulatory oversight under multiple frameworks including REACH regulation in Europe, where it requires registration and safety assessment. The substance falls under CLP regulation with mandatory hazard classification as Carc. 1B and environmental hazard categories. Many countries have established occupational exposure limits and workplace monitoring requirements. Environmental regulations may restrict its release to air, water, and soil. Import/export may require special permits, and users must maintain detailed records of handling, storage, and disposal activities for regulatory compliance and inspection purposes.

Benzo[e]pyrene is available through specialized chemical distributors in Europe, with OYSI serving as a reliable European supplier for this regulated substance. Due to its carcinogenic classification and regulatory requirements, purchases typically require proper documentation including end-use declarations and safety certifications. Buyers must demonstrate appropriate handling facilities and trained personnel. OYSI can provide technical support, regulatory guidance, and proper documentation to ensure compliance with European chemical regulations. Contact OYSI directly for availability, specifications, and regulatory requirements for your specific application and location.
