Overview

(1R,7S)-1,3,4,7,8,9,10,10-octachlorotricyclo[5.2.1.02,6]dec-8-ene (CAS 57-74-9) is a highly chlorinated organochlorine pesticide with exceptional persistence and bioaccumulation properties. This complex tricyclic compound, commonly known as chlordane, represents one of the most structurally intricate organochlorine pesticides ever developed. With its molecular formula C10H6Cl8 and molecular weight of 409.8 g/mol, this substance features eight chlorine atoms strategically positioned on a rigid tricyclic framework, resulting in remarkable chemical stability and resistance to environmental degradation. The specific stereochemistry indicated by the (1R,7S) configuration contributes to its biological activity profile. The compound exhibits significant toxicological properties, classified as a Category 2 carcinogen with acute toxicity warnings. Its classification under ADR Class 6.1 reflects serious health hazards, while GHS pictograms GHS08, GHS07, and GHS09 indicate health, acute toxicity, and environmental dangers respectively. The substance demonstrates extreme aquatic toxicity with both acute and chronic environmental impact classifications, highlighting its persistent bioaccumulative nature. Industrial applications historically included termite control, soil treatment, and structural pest management due to its broad-spectrum insecticidal properties and long-lasting effectiveness. The compound's stability made it particularly valuable for long-term protection applications, though regulatory restrictions have significantly limited its contemporary use. Unlike simpler pesticide formulations containing compounds such as N'-(4-chloro-2-methylphenyl)-N,N-dimethylmethanimidamide, this substance's complex structure provides extended environmental persistence. OYSI maintains technical-grade availability of this specialized organochlorine compound for authorized industrial applications, ensuring compliance with current European chemical regulations and safety protocols.
