DescriptionECHEMI Editorial ReferenceEthoxyquin, chemical formula C11H13NO2, is a synthetic organic compound that belongs to the antioxidant category. This compound usually appears as a colorless or yellowish liquid form and has significant antioxidant properties due to its unique chemical structure. Ethoxyquin plays an important role in the field of industrial and food additives by effectively inhibiting or slowing down oxidation processes, thereby protecting products from deterioration and degradation caused by oxidation. Due to its excellent antioxidant properties, Ethoxyquin is widely used in the oil, feed, cosmetics and pharmaceutical industries to extend the shelf life of the product and maintain its original quality. In addition, this compound requires precise control of reaction conditions during synthesis to ensure the integrity of its structure and the purity of the final product. The discovery and application of Ethoxyquin has provided important technical support for modern industry and food science, helping to improve the stability and safety of products.Basic Info
