2-benzamidobenzoic acid; CAS No.: 579-93-1; 2-benzamidobenzoic acid. PROPERTIES: This compound is a white crystalline solid with molecular formula C13H10N2O2. It has molecular weight of 222.23 g/mol and melting point between 198-202 C. The substance is sparingly soluble in water but dissolves in hot ethanol and DMSO. Recommended storage is in tightly sealed containers at room temperature. As an amide and acid containing compound, it may cause mild skin and eye irritation; standard precautions for laboratory chemicals should be observed. APPLICATIONS: In the field of materials science, this compound serves as monomer for producing polybenzimidazoles used in high-temperature membranes. The benzamido group participates in condensation reactions with diamines to form imidazole rings (Journal of Membrane Science). In pharmaceutical applications, it acts as intermediate for synthesizing anti-tuberculosis agents where the benzamido functionality contributes to inhibition of bacterial cell wall synthesis (Tuberculosis Journal). The carboxylic acid group enables formation of prodrugs with improved solubility. Additionally, it functions as starting material for producing fluorescent probes where the benzoic acid group is converted to fluorescent derivatives through esterification with amino-containing fluorophores (Analytical Chemistry). These applications exploit its combination of amide and carboxylic acid functionalities for constructing polymers and bioactive molecules.
