1. Mainly used as food preservatives and also used in dyes, etc.
2. Used in plant genetic research, and also used as dye intermediates, fungicides and preservatives
3. Sodium benzoate is also an important acid-type food preservative. Converts to the effective form benzoic acid when used. For the scope and dosage of use, please refer to benzoic acid. In addition, it can also be used as a preservative for feed.
4. It is used as a mordant in the dye industry and a plasticizer in the plastic industry. It is also used as an intermediate in organic synthesis such as spices.
