Potassium 2-ethylhexanoate, also known as potassium iso-octanoate, is a chemical used to convert the tert-butylammmonium salt of clavulanic acid into potassium clavulanate (clavulanate potassium).^[1] It is also used as a corrosion inhibitor in automotive antifreeze and as a catalyst for polyurethane systems.^[2]
