Pentacyclo[10.7.1.02,7.08,20.013,18]icosa-1(19),2(7),3,5,8(20),9,11,13,15,17-decaene

Pentacyclo[10.7.1.02,7.08,20.013,18]icosa-1(19),2(7),3,5,8(20),9,11,13,15,17-decaene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C20H12 and CAS number 205-99-2. This complex organic compound features a highly condensed ring structure with multiple fused benzene rings, giving it a molecular weight of 252.3 g/mol. It is classified as a Category 1B carcinogen and poses significant environmental hazards to aquatic life.

This PAH compound typically appears as a crystalline solid at room temperature with a yellowish to pale color. Due to its highly aromatic and hydrophobic nature, it exhibits very low water solubility but dissolves readily in organic solvents such as benzene, toluene, and dichloromethane. The compound has a relatively high melting point and low vapor pressure, characteristics typical of large polycyclic aromatic hydrocarbons with extensive conjugated ring systems.

This compound is primarily used in research applications, particularly in studies involving polycyclic aromatic hydrocarbons and their environmental fate. It serves as a reference standard in analytical chemistry for PAH identification and quantification methods. Industrial applications may include use as an intermediate in organic synthesis or in specialized chemical research. Due to its carcinogenic classification, its commercial applications are highly restricted and subject to stringent regulatory controls.

Safe handling requires complete personal protective equipment including nitrile gloves, safety goggles, and respiratory protection due to its Category 1B carcinogenic classification. Work must be conducted in a well-ventilated fume hood to prevent inhalation exposure. Avoid skin contact and implement strict hygiene measures including immediate washing after handling. Use appropriate engineering controls and ensure all personnel are trained in carcinogen handling procedures according to occupational safety regulations.

Proper storage requires a cool, dry, well-ventilated area away from heat sources and incompatible materials. Store in tightly sealed, labeled containers in a designated carcinogen storage area with restricted access. Keep away from oxidizing agents and strong acids. Implement secondary containment to prevent environmental release due to its aquatic toxicity classification. Regular inventory checks and proper segregation from other chemicals are essential for safe storage management.

Immediate skin contact requires thorough washing with soap and water for at least 15 minutes while removing contaminated clothing. For eye contact, flush immediately with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately and monitor breathing. Due to the carcinogenic nature, seek immediate medical evaluation for any exposure incident and inform healthcare providers of the specific substance and its hazard classification.

Disposal must comply with hazardous waste regulations as a carcinogenic substance with aquatic toxicity. Contact licensed hazardous waste disposal companies for proper treatment, typically involving high-temperature incineration in approved facilities. Never dispose of via regular waste streams or sewage systems due to environmental persistence and toxicity. Maintain detailed waste disposal records and follow local, national, and European waste management directives for carcinogenic substances.

Transportation follows ADR Class 9 (Miscellaneous dangerous goods), Packing Group III requirements. Use appropriate UN specification packaging with proper labeling including GHS08 (health hazard) and GHS09 (environmental hazard) pictograms. Transport documents must include the correct shipping name, hazard class, and emergency response information. Ensure compliance with dangerous goods transport regulations and use certified carriers experienced in handling carcinogenic materials.

Yes, this compound is subject to stringent regulations under REACH and CLP due to its Category 1B carcinogenic classification and aquatic toxicity. It requires safety data sheets, hazard communication, and may be subject to authorization requirements. Occupational exposure limits apply, and workplace health surveillance may be mandatory. Environmental release reporting and restriction on consumer uses are likely enforced under various European chemical safety directives.

OYSI serves as a reliable European distributor for this specialized chemical compound, providing proper documentation and regulatory compliance support. As a professional chemical distributor, OYSI ensures appropriate handling, packaging, and transport according to ADR and CLP requirements. Due to the carcinogenic classification, purchases are typically restricted to qualified industrial and research customers with appropriate safety measures and regulatory authorizations in place.
