Overview

2,2,2-trichloro-1,1-bis(4-chlorophenyl)ethanol (CAS 115-32-2) is an organochlorine compound with pentachlorinated structure and alcohol functionality. This highly chlorinated aromatic alcohol belongs to the family of polychlorinated organic compounds, characterized by its molecular formula C14H9Cl5O and molecular weight of 370.5 g/mol. The compound features a central ethanol backbone substituted with five chlorine atoms: three on the terminal carbon and one on each of the two para-chlorophenyl rings. This extensive chlorination pattern significantly influences both its chemical properties and environmental behavior. From a safety perspective, 2,2,2-trichloro-1,1-bis(4-chlorophenyl)ethanol is classified under multiple hazard categories including acute toxicity (Category 4), skin irritation (Category 2), and skin sensitization (Category 1). The compound exhibits significant aquatic toxicity, classified as both acute and chronic aquatic hazard Category 1, requiring careful environmental consideration during handling and disposal. The GHS07 and GHS09 pictograms reflect its health and environmental hazards, with ADR Class 9 classification for transport as a miscellaneous dangerous substance. Industrial applications typically involve its use as an intermediate in organic synthesis and specialized chemical manufacturing processes. The compound's unique chlorination pattern makes it valuable in the production of certain agrochemicals and as a synthetic building block for more complex organochlorine structures. Unlike related compounds such as 2,6-dichloro-4-(trifluoromethyl)aniline, this alcohol derivative offers specific reactivity through its hydroxyl functionality combined with the electron-withdrawing effects of multiple chlorine substituents. OYSI maintains reliable supply chains for 2,2,2-trichloro-1,1-bis(4-chlorophenyl)ethanol, supporting various industrial applications across European markets with comprehensive technical documentation and regulatory compliance support.
