Overview

1,2,3,4,6,7,8,9,10,10-decachloropentacyclo[5.3.0.02,6.03,9.04,8]decan-5-one (CAS 143-50-0) is a highly chlorinated organic compound with exceptional chemical stability and significant environmental persistence. This complex polychlorinated ketone represents one of the most heavily chlorinated organic molecules in industrial chemistry, featuring ten chlorine atoms arranged around a distinctive pentacyclic carbon framework. With a molecular formula of C10Cl10O and molecular weight of 490.6 g/mol, this compound exhibits remarkable thermal stability and resistance to degradation, properties that have historically made it valuable in specialized industrial applications requiring extreme chemical inertness. The substance presents significant safety considerations, classified as a Category 2 carcinogen with acute toxicity properties and severe aquatic environmental hazards. Its classification under ADR Class 6.1 reflects its toxic nature, requiring stringent handling protocols and specialized storage conditions. The compound's environmental persistence and bioaccumulation potential necessitate careful waste management and disposal procedures in compliance with European chemical regulations. Unlike simpler aromatic compounds such as N-methylaniline or phenylhydrazine, this highly chlorinated structure demonstrates exceptional resistance to biological and chemical breakdown processes. The extensive chlorination pattern creates a molecule with unique electronic properties and extreme hydrophobic characteristics, distinguishing it from conventional organic chemicals in both behavior and environmental fate. Primary industrial applications include specialized flame retardant formulations, high-temperature lubricant additives, and chemical intermediate synthesis where extreme stability is required. The compound also finds use in research applications studying chlorinated organic chemistry and environmental fate modeling. OYSI maintains availability of this specialized chemical compound with comprehensive safety documentation and regulatory compliance support for qualified industrial customers.
