In the realm of fine chemicals, 3-Aminobenzoic Acid (CAS 99-05-8) is a compound of significant interest to researchers and industrial chemists alike. Known for its dual functionality and versatility, this aromatic compound serves as a critical intermediate in various synthesis pathways. Understanding its physico-chemical properties is key to leveraging its full potential in diverse applications. As a leading chemical supplier, we provide comprehensive information to aid your procurement and research efforts.

3-Aminobenzoic Acid, often referred to as m-aminobenzoic acid, possesses a molecular formula of C7H7NO2 and a molecular weight of 137.14. Its structure, featuring an amino group (-NH2) and a carboxylic acid group (-COOH) in a meta position on a benzene ring, dictates its reactivity and solubility. Typically appearing as a white to light yellow crystalline powder, its purity is a critical factor, often specified at a minimum of 99.0% for demanding applications.

The solubility profile of 3-Aminobenzoic Acid is noteworthy. It is readily soluble in acetone, boiling water, hot alcohol, hot chloroform, and ether. However, it exhibits limited solubility in cold water, cold alcohol, and cold chloroform, and is practically insoluble in non-polar solvents like benzene and gasoline. This differential solubility can be exploited during purification processes or in specific reaction environments. The compound is also known to be sweet-tasting and can sublime, indicating its thermal behavior under certain conditions.

The primary application of 3-Aminobenzoic Acid lies in its use as an intermediate for synthesizing other complex chemicals. Historically, it has been integral to the production of azo dyes, contributing vibrant colors and stability to textiles and other materials. Furthermore, its role in the pharmaceutical industry is substantial, serving as a building block for various APIs and related compounds, including diagnostic agents. For these applications, sourcing high-purity material from reliable manufacturers is paramount.

When considering the purchase of 3-Aminobenzoic Acid, it is advisable to seek out suppliers who can provide detailed technical data sheets and confirm batch-to-batch consistency. For B2B customers, establishing a relationship with a reputable manufacturer in China ensures access to competitive pricing and a reliable supply chain. Inquiring about sample availability and requesting a formal quotation are essential steps in the procurement process to verify that the material meets your specific project requirements. The versatility and established utility of 3-Aminobenzoic Acid make it a staple in many chemical synthesis laboratories and industrial production facilities.
