Sodium 2-hydroxybenzenesulfonate(CAS: 1300-51-2)

Sodium 2-hydroxybenzenesulfonate is a crystalline solid with a molecular weight of approximately 228.14 g/mol. It is slightly soluble in water and has a low reactivity under normal conditions. It forms orthorhombic crystals and can be stable up to 150°C without decomposition.

Sodium 2-hydroxybenzenesulfonate is synthesized by reacting 2-hydroxybenzenesulfonic acid with sodium hydroxide. Commonly, this involves the substitution of a hydrogen atom on the aromatic ring with a sodium ion, yielding a sodium salt. The reaction is typically conducted in water at room temperature with good selectivity and yield.

Sodium 2-hydroxybenzenesulfonate finds applications in pharmaceuticals, where it serves as a buffer and stabilizer; in polymers, where it is used as a plasticizer; and in sensors, where it can be employed as a pH indicator. It is also utilized in the semiconductor industry for cleaning and etching processes.

When handling Sodium 2-hydroxybenzenesulfonate, it is important to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Ensure the use of a fume hood to minimize inhalation risks. In case of a spill, use appropriate absorbent materials and consult the safety data sheet (SDS) for further instructions. Storage should be in a cool, dry place, away from strong acids and oxidizers.
