Methyl gallate is widely used in the pharmaceutical and cosmetic industries due to its antioxidant and anti-inflammatory properties. In pharmaceuticals, it is employed as an active ingredient in formulations aimed at treating conditions like oxidative stress-related diseases and skin disorders. Its ability to scavenge free radicals makes it valuable in anti-aging skincare products, where it helps protect the skin from environmental damage and reduces signs of aging. Additionally, methyl gallate is utilized in food preservation to extend shelf life by preventing oxidation. It also finds applications in research as a standard compound for studying antioxidant mechanisms and evaluating the efficacy of other antioxidants.
