(1R,2R,3R,6S,7S,8S,9S,11R)-3,4,5,6,13,13-hexachloro-10-oxapentacyclo[6.3.1.13,6.02,7.09,11]tridec-4-ene

(1R,2R,3R,6S,7S,8S,9S,11R)-3,4,5,6,13,13-hexachloro-10-oxapentacyclo[6.3.1.13,6.02,7.09,11]tridec-4-ene is an organochlorine compound with molecular formula C12H8Cl6O and CAS number 72-20-8. This complex pentacyclic molecule contains six chlorine atoms and has a molecular weight of 380.9 g/mol. It is classified as highly toxic and environmentally hazardous, requiring careful handling and specialized knowledge for safe use.

This organochlorine compound is a solid at room temperature with high chlorine content contributing to its stability and persistence. The molecular structure features multiple ring systems with six chlorine substituents, making it lipophilic and poorly water-soluble. Its high molecular weight of 380.9 g/mol and complex stereochemistry result in specific physical characteristics typical of heavily chlorinated organic compounds, including low volatility and high chemical stability.

This highly chlorinated compound is primarily used in specialized industrial applications requiring persistent organochlorine chemistry. Due to its complex structure and high toxicity classification, its applications are limited to specific technical processes under strict regulatory control. Professional users must possess appropriate expertise and safety infrastructure. The compound's unique pentacyclic structure and chlorination pattern make it suitable for specialized research and industrial applications where such specific chemical properties are required.

Safe handling requires comprehensive personal protective equipment including chemical-resistant gloves, protective clothing, eye protection, and respiratory protection due to its Acute Tox. 2 and 3 classifications. Work must be conducted in well-ventilated areas or under fume extraction systems. Avoid skin contact, inhalation, and ingestion. Use appropriate containment measures to prevent environmental release given its aquatic toxicity classification. Only trained personnel should handle this substance following established safety protocols.

Correct storage requires secure, cool, dry conditions away from incompatible materials and ignition sources. Containers must be tightly sealed and properly labeled with appropriate hazard warnings including GHS06 and GHS09 pictograms. Storage areas should have adequate ventilation and spill containment measures. Access must be restricted to authorized personnel only. Regular container inspection is essential to prevent leakage, and storage must comply with local regulations for highly toxic substances.

Immediate medical attention is required due to the substance's high acute toxicity classification. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of clean water for at least 15 minutes. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek emergency medical care. Always consult the safety data sheet and contact poison control centers when necessary.

Disposal must be conducted through licensed hazardous waste disposal facilities capable of handling highly toxic organochlorine compounds. The substance cannot be disposed of in regular waste streams due to its acute toxicity and environmental hazard classifications. Incineration at high temperatures in specialized facilities is typically required. All disposal activities must comply with local, national, and EU waste regulations. Contaminated containers and materials require similar specialized disposal treatment.

Transportation is classified under ADR Class 6.1 (Toxic substances), Packing Group I, indicating maximum danger level for toxic materials. Specialized packaging, labeling, and documentation are mandatory. Vehicles must carry appropriate emergency equipment and drivers require ADR certification. Emergency response information must accompany shipments. Transport must follow dangerous goods regulations with proper hazard identification including toxic substance markings. Only certified carriers experienced in handling highly toxic chemicals should transport this substance.

This substance is subject to comprehensive EU chemical regulations including REACH registration requirements and CLP classification obligations. While not currently listed as an SVHC, its high acute toxicity and environmental hazard classifications impose strict handling, storage, and disposal requirements. Users must maintain safety data sheets and implement appropriate risk management measures. National restrictions may apply, and professional users must ensure compliance with occupational health and environmental protection regulations before use.
