Understanding the chemical makeup and inherent properties of a compound is fundamental for any chemist or formulator looking to utilize it effectively. Sodium 3-Sulfobenzoate (CAS 17625-03-5) is a compound that garners significant interest due to its unique structure and the resulting chemical characteristics. As a manufacturer and supplier of this important intermediate, we aim to shed light on its fundamental attributes that make it valuable in synthesis and other industrial applications.

Chemical Structure and Nomenclature

Sodium 3-Sulfobenzoate, with the molecular formula C7H5NaO5S and a molecular weight of 224.17, is characterized by a benzene ring substituted at the meta (3-) position with both a carboxylate group (-COO⁻) and a sulfonate group (-SO₃⁻), with a sodium cation (Na⁺) acting as the counterion. Its IUPAC name is sodium;3-carboxybenzenesulfonate. This arrangement is crucial: the sulfonate group significantly increases water solubility, while the carboxylate group offers a site for further chemical modification or salt formation. These features make it a versatile building block for many syntheses.

Key Properties for Application

The physical and chemical properties of Sodium 3-Sulfobenzoate dictate its utility:

  • Appearance: It typically presents as a white crystalline powder.
  • Purity: High purity, often exceeding 99%, is a critical parameter for its use in sensitive applications like pharmaceutical intermediate synthesis.
  • Water Solubility: The presence of the ionic sulfonate group renders it highly soluble in water, a property often exploited in formulations and reactions requiring aqueous media.
  • Melting Point: It generally has a high melting point, often reported as >300°C, indicating thermal stability.
  • Chemical Reactivity: The carboxylate group can undergo esterification, amidation, or other reactions typical of carboxylic acids. The aromatic ring itself can also be subject to further electrophilic or nucleophilic substitutions, depending on reaction conditions.

For professionals looking to buy Sodium 3-Sulfobenzoate, understanding these properties allows for informed selection and application. Whether used as a pharmaceutical intermediate or an organic synthesis raw material, its inherent characteristics are key to successful outcomes.
