Used primarily in the production of plasticizers, especially for polyvinyl chloride (PVC), to improve flexibility and durability in products like cables, flooring, and films. It is a key component in synthesizing di(2-ethylhexyl) phthalate (DEHP) and other ester-based plasticizers.

Also serves as an intermediate in manufacturing lubricants, surfactants, synthetic rubber, and cleaning chemicals. Employed in solvent extraction processes, particularly in the purification of antibiotics and metal ions.

Finds use in formulating coatings, adhesives, and printing inks due to its solvency and stability.

Additionally, it acts as a precursor in the synthesis of 2-ethylhexyl acrylate for specialty polymers.

In the fragrance and cosmetics industry, it is used as a solvent or carrier for perfumes and scents due to its mild odor and slow evaporation, enhancing fragrance longevity.
