Naphthenic acids, copper salts (CAS 1338-02-9) are a group of chemical compounds formed by the reaction of naphthenic acids with copper. These substances typically exhibit characteristics associated with both naphthenic acids and metal salts. Naphthenic acids are carboxylic acids derived from petroleum, characterized by their cyclic and branched structures, which contribute to their unique properties, such as solubility in organic solvents and varying degrees of acidity. The copper salts of these acids often display enhanced stability and can act as catalysts or additives in various industrial applications, including lubricants and corrosion inhibitors. They may also exhibit antimicrobial properties, making them useful in certain formulations. The physical state of naphthenic acids, copper salts can vary, but they are generally solid or semi-solid at room temperature. Safety considerations include potential toxicity and environmental impact, necessitating careful handling and disposal. Overall, these compounds play a significant role in industrial chemistry, particularly in applications related to petroleum and metalworking.

Copper naphthenate is a cross-linking agent that contains copper and nitrogen atoms. It reacts with potassium dichromate, sodium carbonate, and other substances to form a copper complex. Copper naphthenate is used in the manufacture of biodiesel as a preservative. The product also has insecticidal properties, which have been shown to be due to its ability to inhibit the activity of chitin synthase enzymes found in insects. Copper naphthenate has been shown to be effective as a contraceptive when used vaginally and may also be used topically on the skin for this purpose. This product is acidic and should not be mixed with other acidic substances or materials such as plastics or rubber.
