Solubility: Slightly soluble in cold water, soluble in hot water and ether, slightly soluble in ethanol

　　Main Uses

　　Isooctanoic acid and its derivatives are widely used due to their low volatility, good solubility, and stability brought about by their branched-chain structure:

　　Metal soap raw materials: Metal soaps formed by isooctanoic acid and metals (Zn, Co, Ca, Pb, etc.) constitute the most important application field:

　　Cobalt isooctanoate, Manganese isooctanoate: Used as driers for coatings (e.g., alkyd resin paints) to promote oxidative cross-linking of the paint film and accelerate drying.

　　Zinc isooctanoate: Used in plastic stabilizers (e.g., PVC heat stabilizers), rubber vulcanization accelerators, or as preservatives in cosmetics.

　　Calcium isooctanoate: Used as a lubricant additive (anti-wear, anti-rust) or as a feed additive (supplementing calcium).

　　Ester intermediates: Isoctanoate esters (e.g., esters with ethylene glycol, pentaerythritol) can be used as plasticizers (substituting phthalates), synthetic lubricants (high-temperature resistant, low volatility), and emollients in cosmetics.

　　Pharmaceuticals and pesticides: Used as intermediates in the synthesis of antibiotics, antiepileptic drugs, or active ingredients in herbicides and insecticides.

　　Others: Used in the preparation of surfactants (e.g., sodium isooctanoate), textile auxiliaries (softeners, leveling agents), or as metal extractants (separating rare metals)
