Sodium 2-ethylhexanoate is a white to off-white hygroscopic crystalline powder with the chemical formula C₈H₁₅NaO₂. It is the sodium salt of 2-ethylhexanoic acid and is highly soluble in water and various organic solvents such as methanol and ethanol. This compound is widely utilized as a chemical intermediate in the synthesis of metal 2-ethylhexanoates, which serve as catalysts, stabilizers, and additives in diverse industrial applications. Its roles span across the pharmaceutical, polymer, coatings, and fuel industries, owing to its effectiveness as a salt-forming agent, acid scavenger, and catalyst precursor.

Sodium 2-ethylhexanoate can be used as:

• A polymer stabilizer and crosslinking agent in the stabilization of polymers and as a crosslinking agent in the manufacture of coatings and adhesives, enhancing durability and performance.
• A catalyst precursor in the synthesis of metal 2-ethylhexanoates, such as cerium(III) 2-ethylhexanoate, which are used as homogeneous catalysts to improve combustion efficiency in fuels like LPG.
• A salt-forming agent in the production of pharmaceutical compounds, including antibiotics like sulbactam sodium and cefuroxime sodium.
• An energy-saving additive in fuels, contributing to improved combustion and reduced emissions.
