Product Introduction

6-Ethoxy-2,2,4-Trimethyl-1,2-Dihydroquinoline, commonly known as Ethoxyquin, is a quinoline-based synthetic antioxidant widely recognized for its efficacy in various applications. Its chemical name is 6-Ethoxy-1,2-dihydro-2,2,4-trimethylquinoline, with a molecular formula of C14H19NO and a molecular weight of 217.31 g/mol. The CAS number for this compound is 91-53-2. As a trusted product from a leading manufacturer in China, it is valued for its stability and performance in preserving quality across multiple industries.

Physical and Chemical Properties

This compound typically appears as a clear light yellow to dark brown viscous liquid, though it may darken upon exposure to air and light due to polymerization. It possesses a mercaptan-like odor and has a density of approximately 1.03 g/mL at 20°C. The melting point is below 0°C, and while its boiling point is not precisely defined, it remains stable under normal conditions but may polymerize at temperatures above 160°C (320°F). Ethoxyquin is insoluble in water but soluble in organic solvents such as benzene, chloroform, and ethanol, making it versatile for various formulations.

Product Applications

6-Ethoxy-2,2,4-Trimethyl-1,2-Dihydroquinoline is primarily utilized as an antioxidant and preservative. It is widely applied in animal feed to prevent lipid peroxidation and fat rancidity, ensuring the nutritional quality of poultry, salmon, and beef products. Additionally, it serves as a pesticide to control scald on pears post-harvest and preserves color in spices like paprika and chili powder. Its effectiveness as a food antioxidant, combined with its availability from a reputable supplier in China, makes it a preferred choice for food, feed, and agricultural industries seeking reliable preservation solutions.
