Overview

Diethoxyphosphoryl diethyl phosphate (CAS 107-49-3) is an organophosphate compound with high acute toxicity and significant environmental impact potential. This phosphorus-containing chemical, with the molecular formula C8H20O7P2 and a molecular weight of 290.19 g/mol, belongs to the class of organophosphate esters that have found widespread industrial applications despite their inherent hazardous properties. The compound presents serious safety considerations due to its classification under Acute Toxicity Categories 1 and 2, requiring the "Danger" signal word and displaying both the skull and crossbones (GHS06) and environmental hazard (GHS09) pictograms. Its ADR classification as Class 6.1 reflects its toxic nature during transport and handling. The substance also carries an Aquatic Acute 1 classification, indicating severe immediate toxicity to aquatic life, which necessitates careful environmental management protocols. Like other organophosphate compounds such as diethoxy-(2-ethylsulfanylethoxy)-sulfanylidene-lambda5-phosphane, this chemical requires specialized handling procedures and appropriate personal protective equipment. Its phosphate ester structure makes it particularly reactive and potentially bioactive, characteristics that both enable its industrial utility and demand stringent safety measures. Primary industrial applications include its use as an intermediate in the synthesis of flame retardants, plasticizers, and specialty chemical formulations. The compound also serves in the production of certain pesticide formulations and as a chemical intermediate in pharmaceutical manufacturing processes. These applications leverage its phosphorus-containing structure and reactivity profile. OYSI provides diethoxyphosphoryl diethyl phosphate to qualified industrial customers with comprehensive safety documentation and technical support to ensure proper handling and regulatory compliance.
