3-Aminobenzoic Acid (CAS 99-05-8) is a fundamental chemical intermediate that finds extensive use across various industrial sectors, most notably in the production of pharmaceuticals and dyes. A thorough understanding of its chemical profile, including its physical and chemical properties, is essential for chemists and procurement specialists. As a manufacturer specializing in fine chemicals, we provide insights into this crucial compound to support your purchasing decisions.

At its core, 3-Aminobenzoic Acid is an aromatic compound with the molecular formula C7H7NO2 and a molecular weight of 137.14. Its structure is defined by a benzene ring substituted with both an amino group (-NH2) and a carboxylic acid group (-COOH) at the meta position. This bifunctionality is the source of its reactivity and utility. Typically, the compound is supplied as a white to light yellow crystalline powder, with a high purity standard often set at 99.0% minimum, which is critical for its intended applications.

Key physico-chemical properties include its melting point, which is generally reported between 172-180°C, indicating its solid state at room temperature. Its solubility is also a defining characteristic: it is soluble in polar organic solvents like acetone and ethanol, and also in boiling water, while showing limited solubility in cold water and being largely insoluble in non-polar solvents like benzene and gasoline. This solubility profile is important for reaction design and purification strategies.

From a manufacturing perspective, 3-Aminobenzoic Acid is often synthesized through the reduction of 3-nitrobenzoic acid. Various reduction methods, such as catalytic hydrogenation using catalysts like Palladium on carbon or Raney nickel, or chemical reduction using iron powder in acidic or neutral conditions, are employed. These processes are optimized to achieve high yields and the required purity. For businesses looking to buy this chemical, understanding these production methods can provide insight into potential quality variations and the supplier's expertise.

The applications of 3-Aminobenzoic Acid are predominantly as an intermediate. In the pharmaceutical industry, it is a precursor for APIs and diagnostic agents. In the dye industry, it plays a critical role in the synthesis of azo dyes, contributing to color depth and stability. The consistent demand for these applications underscores the need for reliable supply. For companies seeking to purchase 3-Aminobenzoic Acid, partnering with a manufacturer known for rigorous quality control and consistent production standards is advisable.
