Sodium erythorbate, also known as sodium D-isoascorbate, is a white to off-white or yellow-white crystalline powder or granules with the formula C6H7NaO6 and molecular weight 198.11 g/mol. It is slightly salty, almost odorless, highly soluble in water (forming clear solutions), and stable under normal conditions but decomposes in light or heat. Derived from erythorbic acid, it acts as a stereoisomer of ascorbic acid and is produced via fermentation or synthesis.
