Overview

2-(2,4,5-trichlorophenoxy)ethyl 2,2-dichloropropanoate (CAS 136-25-4) is a chlorinated organic compound with selective herbicidal properties and moderate aquatic toxicity. This highly chlorinated chemical compound represents a specialized pesticide intermediate combining both phenoxyacetic and dichloropropanoic acid functionalities. With its molecular formula C11H9Cl5O3 and molecular weight of 366.4 g/mol, this substance demonstrates the structural complexity typical of organochlorine agricultural chemicals developed for selective weed control applications. The compound exhibits moderate acute toxicity (Acute Tox. 4) requiring careful handling protocols, while its chronic aquatic toxicity classification (Aquatic Chronic 2) necessitates environmental protection measures during storage and application. The assigned GHS07 and GHS09 pictograms reflect both its human health hazards and environmental concerns, particularly regarding aquatic ecosystems. As a Class 9 ADR substance, it requires specific transportation and storage considerations under hazardous materials regulations. Safety protocols must address its potential for skin and eye irritation, along with possible respiratory effects upon inhalation. Workers handling this material should utilize appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and adequate ventilation systems. The compound's environmental persistence characteristics demand controlled application methods to minimize groundwater contamination and non-target species exposure. Primary industrial applications include formulation of selective herbicides for agricultural crop protection and specialized vegetation management in industrial settings. The compound may also serve as a chemical intermediate in the synthesis of related pesticide active ingredients, similar to how other complex organochlorine compounds like diethyl 2-[(4-ethoxyanilino)methylidene]propanedioate function in agricultural chemistry applications. OYSI maintains reliable supply chains for this specialized chemical compound, supporting European industrial customers with comprehensive technical documentation and regulatory compliance support.
