2-Sulfobenzoic acid

Description:

2-Sulfobenzoic acid, also known as o-sulfobenzoic acid, is an aromatic sulfonic acid characterized by the presence of a sulfonic acid group (-SO3H) attached to a benzene ring that also contains a carboxylic acid group (-COOH). This compound is typically a white to off-white crystalline solid that is soluble in water due to the polar nature of its functional groups. It exhibits acidic properties, with the ability to donate protons in solution, making it useful in various chemical reactions and applications. 2-Sulfobenzoic acid is often utilized in organic synthesis, particularly in the preparation of dyes, pharmaceuticals, and as a reagent in analytical chemistry. Its sulfonic acid group enhances its reactivity and solubility, allowing it to participate in electrophilic substitution reactions. Additionally, it can serve as a precursor for the synthesis of other sulfonated compounds. Safety data indicates that, like many sulfonic acids, it should be handled with care, as it can be irritating to skin and eyes.

CAS: 632-25-7

2-Sulfobenzoic acid is a water soluble, hydrophilic compound. It has a proton NMR spectrum with a single peak at 4.2 ppm. 2-Sulfobenzoic acid is an electron-withdrawing group that forms hydrogen bonding interactions with water molecules and chelate ligands. The disulfide bond in the molecule is important for its structural stability and anticancer activity. The frequency shift of the proton NMR spectrum upon addition of nucleophiles indicates that 2-sulfobenzoic acid can act as a nucleophile itself, as well as react with nucleophiles such as thiols, amines, and alcohols.
2-Sulfobenzoic acid can be used to synthesize covalent linkages between proteins and DNA, which may have applications in cancer research and other fields.
