Overview
1,5,7,8,9,10,10-heptachlorotricyclo[5.2.1.02,6]deca-3,8-diene (CAS 76-44-8) is a highly chlorinated organic compound with significant toxicological properties and environmental persistence. This heptachlorinated tricyclic compound, with molecular formula C10H5Cl7 and molecular weight 373.3 g/mol, represents a complex organochlorine structure featuring multiple chlorine substituents on a rigid tricyclic framework. The compound's extensive chlorination contributes to its chemical stability and resistance to degradation, while simultaneously raising significant safety and environmental concerns due to its classification under multiple hazard categories. The substance exhibits considerable toxicological risks, classified as a Category 2 carcinogen and Category 3 acute toxicant, requiring careful handling protocols and appropriate safety measures. Its environmental impact is particularly noteworthy, with classifications as both Aquatic Acute 1 and Aquatic Chronic 1, indicating severe immediate and long-term effects on aquatic ecosystems. The ADR Class 6.1 designation reflects its toxic nature during transportation, necessitating specialized shipping requirements. Industrial applications of this organochlorine compound typically include use as an intermediate in chemical synthesis processes, flame retardant formulations, and specialized chemical manufacturing where its stability and chlorine content provide specific technical advantages. The compound's unique tricyclic structure makes it valuable in applications requiring thermal stability and chemical resistance, though its use is increasingly restricted due to environmental and health considerations. Unlike simpler compounds such as cadmium-based materials including cadmium(2+);silicon(4+);hexafluoride, this organochlorine structure offers different chemical properties suited to specific industrial processes. OYSI maintains availability of this technical-grade compound for qualified industrial customers with appropriate handling capabilities and regulatory compliance.
