Benzoic acid, 2-sulfo-, ammonium salt (1:1)

Description:
Benzoic acid, 2-sulfo-, ammonium salt (1:1), commonly referred to as ammonium 2-sulfobenzoate, is an organic compound characterized by its sulfonic acid and carboxylic acid functional groups. It appears as a white to off-white crystalline solid and is soluble in water, which enhances its utility in various applications. The presence of the sulfonate group contributes to its high polarity and makes it an effective surfactant and emulsifying agent. This compound is often used in the food and pharmaceutical industries as a preservative and pH regulator. Additionally, it can serve as a reagent in organic synthesis and analytical chemistry. Its ammonium salt form indicates that it can act as a source of ammonium ions in solution, which may influence its reactivity and interactions in biological systems. Safety data suggests that while it is generally considered to have low toxicity, appropriate handling and safety measures should be observed to avoid potential irritation or adverse effects.
