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 system with multiple fused benzene rings. With a molecular weight of 252.3 g/mol, it belongs to the category 1B carcinogens and poses significant environmental hazards to aquatic ecosystems.

This polycyclic aromatic hydrocarbon is typically a solid crystalline substance at room temperature with a yellowish appearance. As a highly condensed PAH structure, it exhibits very low water solubility but shows good solubility in organic solvents such as benzene, toluene, and chlorinated solvents. The compound has a high melting point due to its rigid polycyclic structure and strong intermolecular interactions, making it thermally stable under normal conditions.

This polycyclic aromatic hydrocarbon is primarily used in research applications and specialized chemical synthesis. It serves as an intermediate in organic chemistry research, particularly in studies involving PAH chemistry and photophysical properties. Due to its carcinogenic classification and environmental hazards, its industrial applications are highly restricted and mainly limited to laboratory research, analytical standards, and specialized material science applications under controlled conditions.

Safe handling requires comprehensive personal protective equipment including nitrile gloves, safety goggles, and respiratory protection due to its carcinogenic properties. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin and eye contact completely, and never eat, drink, or smoke while handling. Regular monitoring of workplace air quality is essential, and all personnel must receive specialized training on carcinogen handling procedures before use.

Storage requires cool, dry conditions away from direct sunlight in tightly sealed containers to prevent contamination and degradation. The substance must be stored in designated areas with restricted access due to its carcinogenic classification. Keep away from strong oxidizing agents and sources of ignition. Storage areas should have appropriate ventilation, spill containment measures, and clear hazard labeling. Regular container inspection is necessary to ensure integrity and prevent environmental release.

Immediate action is crucial due to carcinogenic risks. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for 15 minutes and remove contact lenses if present. For inhalation, move to fresh air immediately. In all cases, seek immediate medical attention and inform medical personnel of the carcinogenic nature of the substance and provide safety data sheet information.

Disposal must comply with local hazardous waste regulations and be handled by licensed hazardous waste contractors. This carcinogenic PAH cannot be disposed of in regular waste streams and requires specialized high-temperature incineration facilities. All contaminated materials including gloves, containers, and cleaning materials must be treated as hazardous waste. Documentation of disposal methods and quantities is mandatory for regulatory compliance and environmental protection.

Transportation follows ADR Class 9 regulations as a miscellaneous dangerous substance with Packing Group III classification. Proper packaging must meet UN specification standards with appropriate hazard labels including GHS08 and GHS09 pictograms. Transport documentation must include proper shipping names, hazard classifications, and emergency response information. Drivers require specialized dangerous goods training, and vehicles must carry appropriate safety equipment and spill response materials for environmental protection.

Yes, this substance is subject to strict regulatory oversight under REACH and CLP regulations due to its carcinogenic classification. As a Category 1B carcinogen with aquatic toxicity, it requires comprehensive risk assessments and exposure control measures. Users must comply with occupational exposure limits, implement strict handling protocols, and maintain detailed usage records. Special authorization may be required for certain applications, and regulatory reporting obligations apply to manufacturers and importers.
