1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one is a highly chlorinated organic compound with the molecular formula C10Cl10O and CAS number 143-50-0. This substance features a complex pentacyclic structure with ten chlorine atoms and one ketone functional group. With a molecular weight of 490.6 g/mol, it belongs to the class of polychlorinated compounds and is classified as a category 2 carcinogen with acute toxicity properties.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one is a solid compound at room temperature due to its high molecular weight of 490.6 g/mol and extensive chlorination. The substance typically appears as a crystalline solid with limited water solubility due to its highly chlorinated structure. Its physical properties are influenced by the rigid pentacyclic framework and the presence of multiple chlorine substituents, which contribute to its stability and persistence.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one is primarily used in specialized chemical research and industrial applications requiring persistent organic compounds. Due to its highly chlorinated structure and stability, it may serve as an intermediate in organic synthesis or as a reference standard in analytical chemistry. However, its use is strictly regulated due to its carcinogenic properties and environmental persistence, limiting its applications to controlled professional environments.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one requires strict safety measures due to its Acute Tox. 3 and Carc. 2 classifications. Essential protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection in well-ventilated areas. Work should be conducted in fume hoods to prevent inhalation exposure. Avoid direct skin contact and ingestion. Emergency procedures and safety data sheets must be readily available, and only trained personnel should handle this substance.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Use tightly sealed, chemically resistant containers to prevent contamination and vapor release. Storage areas should be secured and accessible only to authorized personnel due to the substance's carcinogenic and toxic properties. Implement appropriate spill containment measures and ensure compliance with local hazardous material storage regulations.

Immediate action is required upon contact with 1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one due to its acute toxicity. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush with clean water for 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always contact poison control or emergency services promptly.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one requires specialized hazardous waste disposal due to its carcinogenic properties and environmental persistence (Aquatic Acute 1, Aquatic Chronic 1). Disposal must be conducted through licensed hazardous waste contractors following local and EU regulations. High-temperature incineration in authorized facilities is typically required. Never dispose of through regular waste streams or release into the environment. Maintain detailed disposal documentation for regulatory compliance and traceability.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one is classified under ADR Class 6.1 (toxic substances), Packing Group III for transportation. Packages must comply with UN packaging requirements and bear appropriate hazard labels (GHS06, GHS08, GHS09). Transport documentation must include proper shipping names, hazard classifications, and emergency response information. Only authorized carriers experienced in hazardous material transport should handle shipments, ensuring compliance with international dangerous goods regulations.

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one is subject to extensive EU regulations including REACH registration requirements and CLP classification as Carc. 2 and Acute Tox. 3. While not currently listed as an SVHC, its carcinogenic properties and environmental impact require strict compliance with occupational exposure limits and environmental protection measures. Users must maintain safety data sheets, implement risk management measures, and ensure proper worker training and protection protocols.
