  • Applications

    2-Ethylhexyl formate, CAS 5460-45-7, is used as a processing solvent and carrier in coatings, inks, and adhesive formulations, supporting resin solubility and film formation. It also functions as a plasticizer for certain polymers and resins, improving flexibility and processability. It serves as an intermediate in organic synthesis for the preparation of other formate esters. In industrial manufacturing, it can act as a cleaning solvent or degreasing agent in formulations requiring moderate solvency.
