Serves as a precursor in the synthesis of tartaric acid derivatives. Employed in some electroplating baths to stabilize metal ions and improve deposit quality. Occasionally utilized in niche applications in food and beverage as an acidity regulator, though less common than other tartaric acid forms. Also finds use in the preparation of buffer solutions for laboratory research due to its well-defined acid-base properties. Used in analytical chemistry as a reference standard for meso compounds and in stereochemical studies, given its achiral nature despite having chiral centers.
