Description
Dioctyl succinate (CAS 14491-66-8, EC 238-499-4) is a diester of succinic acid and 2-ethylhexanol, also referenced under the names dioctyl butanedioate and Ai3-07873. It carries no assigned E-code and is classified under HS code 29171310 within the esters of acyclic polycarboxylic acids category.
In PVC and polymer compounding, dioctyl succinate functions as a plasticizer by intercalating between polymer chains, reducing intermolecular forces and lowering the glass transition temperature to improve flexibility. In lubricant and metalworking formulations, its ester structure provides a stable base fluid with low volatility and good boundary lubrication characteristics. It also serves as a solvent carrier in coating and adhesive systems.
Dioctyl succinate is supplied as a technical-grade liquid and is subject to REACH registration requirements for EU market placement. Suppliers typically offer it in drums and intermediate bulk containers. Procurement teams should request a full safety data sheet and confirm REACH compliance documentation prior to sourcing.
