Key Properties
n-Propyl gallate (extra pure, antioxidant) is a widely used antioxidant preservative, valued for its effectiveness in food, cosmetic, and pharmaceutical products. It is a derivative of gallic acid and is known for its ability to inhibit oxidative rancidity in fats and oils, thereby extending the shelf life of various formulations. This compound is particularly notable for its high purity level of 98%, making it suitable for sensitive applications where quality is paramount. Its antioxidant properties make it a preferred choice in formulations that require protection against oxidative degradation.
Also known as Propyl gallate, n-Propyl 3,4,5-trihydroxybenzoate.
