Overview
1,3,5,7,8,9,10,10-octachloro-4-oxatricyclo[5.2.1.02,6]dec-8-ene (CAS 297-78-9) is a highly chlorinated organochlorine compound with exceptional chemical stability and potent biological activity. This complex tricyclic molecule, with the molecular formula C9H4Cl8O and a molecular weight of 411.7 g/mol, represents one of the most heavily chlorinated organic compounds used in industrial applications. The substance features a unique oxatricyclic structure containing eight chlorine atoms strategically positioned throughout the molecular framework, contributing to its remarkable chemical resistance and persistence. Its EC number 206-045-4 identifies it within European chemical regulations, where it is classified under multiple hazard categories including Acute Toxicity Category 1 and 2, as well as Aquatic Acute Category 1, reflecting both its potent biological effects and environmental concerns. The compound's highly chlorinated nature places it in a specialized category of organochlorine chemicals, distinct from simpler phosphorus-containing compounds like diethoxyphosphoryl diethyl phosphate, though both classes find applications in industrial chemical processes. Safety considerations are paramount when handling this material, as indicated by the GHS06 and GHS09 pictograms signaling both acute toxicity and environmental hazards. Transportation requires adherence to ADR Class 6.1 regulations for toxic substances. Industrial applications primarily leverage the compound's chemical stability and resistance to degradation in specialized chemical synthesis processes, advanced materials manufacturing, and as an intermediate in the production of specialized industrial chemicals. Its unique molecular architecture makes it particularly valuable in applications requiring extreme chemical resistance. OYSI maintains reliable supply chains for this specialized chemical compound, ensuring availability for qualified industrial customers across Europe.
