C7H5NaO2, commonly known as sodium benzoate, is a widely used food preservative. It is the sodium salt of benzoic acid and is effective in preventing the growth of bacteria, yeast, and fungi in acidic foods and beverages. Sodium benzoate is often found in products like soft drinks, pickles, and salad dressings. This compound is recognized for its safety when used in regulated amounts, as it is generally regarded as safe by the U.S. Food and Drug Administration (FDA). However, excessive consumption can lead to potential health concerns, including allergic reactions in sensitive individuals.
