Pentacyclo[10.7.1.02,11.03,8.016,20]icosa-1(19),2(11),3,5,7,9,12,14,16(20),17-decaene

Pentacyclo[10.7.1.02,11.03,8.016,20]icosa-1(19),2(11),3,5,7,9,12,14,16(20),17-decaene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C20H12 and CAS number 205-82-3. This complex organic compound features a pentacyclic structure with multiple fused benzene rings, giving it a molecular weight of 252.3 g/mol. It is classified as a carcinogenic substance (Category 1B) and poses significant environmental hazards to aquatic ecosystems.

This polycyclic aromatic hydrocarbon typically appears as a solid crystalline material at room temperature due to its high molecular weight of 252.3 g/mol. Like most PAHs, it exhibits low water solubility but dissolves readily in organic solvents such as benzene, toluene, and dichloromethane. The compound demonstrates high thermal stability and low volatility characteristic of complex aromatic ring systems, with strong UV absorption properties typical of conjugated aromatic compounds.

This polycyclic aromatic hydrocarbon serves primarily as a research chemical and analytical standard in environmental monitoring and toxicology studies. It is used in academic and industrial laboratories for studying PAH behavior, developing analytical methods, and conducting environmental fate studies. The compound also finds application in materials science research, particularly in studies involving organic semiconductors and photovoltaic materials due to its extended aromatic system and electronic properties.

Safe handling requires comprehensive personal protective equipment including nitrile gloves, safety goggles, and laboratory coats to prevent skin and eye contact. Work must be conducted in well-ventilated areas or under fume hoods to avoid inhalation exposure. Given its carcinogenic classification (Category 1B), minimize direct contact and use appropriate handling tools. Ensure proper training on carcinogenic substance handling protocols and maintain detailed exposure records. Emergency shower and eyewash stations should be readily accessible.

Store this compound in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Use tightly sealed containers made of chemically compatible materials to prevent contamination and environmental release. Due to its carcinogenic properties, storage areas must be clearly labeled and access restricted to authorized personnel only. Implement secondary containment measures to prevent environmental contamination and maintain inventory records for regulatory compliance.

Immediate decontamination is essential due to the carcinogenic nature of this substance. For skin contact, remove contaminated clothing and wash affected areas thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek medical attention promptly in all exposure cases and inform healthcare providers about the carcinogenic classification of the substance.

Disposal must comply with local, national, and EU waste regulations for carcinogenic and environmentally hazardous substances. This compound requires disposal as hazardous waste through licensed waste management contractors specialized in handling carcinogenic materials. Incineration at high temperatures in approved facilities is typically the preferred method. Never dispose of via regular waste streams or drain systems due to its environmental toxicity. Maintain detailed waste disposal records for regulatory compliance and traceability.

Transportation falls under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III, indicating moderate danger level during transport. Use approved packaging materials that meet UN specifications for Class 9 substances. Proper shipping documentation must include the correct technical name, UN number, and hazard labels. Ensure compliance with ADR regulations for loading, segregation, and vehicle requirements. Transportation should be conducted by certified carriers experienced in handling hazardous chemicals with appropriate emergency response capabilities.

This substance is subject to comprehensive EU chemical regulations including REACH registration requirements and CLP classification as a Category 1B carcinogen. It requires specific labeling with GHS08 (health hazard) and GHS09 (environmental hazard) pictograms and 'Danger' signal word. Although not currently listed as an SVHC, its carcinogenic properties subject it to strict occupational exposure controls. Users must comply with national occupational safety regulations and maintain exposure monitoring records where required.
