What is Dioctyl azelate?
Dioctyl azelate (CAS 103-24-2), also known commercially as bis(2-ethylhexyl) azelate (DOZ), is a synthetic diester plasticizer and lubricant base fluid derived from azelaic acid.
Where is Dioctyl azelate used?
- Plastics compounding: primary or secondary plasticizer for PVC and other polymers needing low-temperature performance, notably wire and cable jacketing, films and flexible profiles
- Synthetic lubricants: base fluid or additive in aviation, automotive and industrial gear oils
- Rubber processing: flexibility and processability in seals, gaskets and automotive components for cold environments
- Metalworking fluids: lubricity and friction reduction
- It is a clear, low-viscosity liquid.
Commercial specifications
- Purity typically 99% or above
- Specifications aligned with plasticizer ester benchmarks: acid value, color, moisture content
- Drum and IBC quantities; bulk tanker options
