For research and development scientists, chemists, and formulators, a thorough understanding of a chemical intermediate's properties and safe handling procedures is fundamental to successful project execution. 3-Aminophthalic Acid (CAS: 5434-20-8) is a compound that warrants detailed attention due to its utility in complex synthesis pathways. As a leading 3-Aminophthalic Acid manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. prioritizes providing comprehensive technical information to support professionals in the chemical industry.

3-Aminophthalic Acid presents as a yellow crystalline powder, indicating its solid state at room temperature. Its molecular formula, C8H7NO4, and molecular weight of 181.15 g/mol are key identifiers for chemists. Physically, it has a density of 1.551 g/cm³ and a relatively high melting point ranging from 180-185°C (lit.), suggesting good thermal stability under normal processing conditions. The boiling point of 436.4°C at 760 mmHg further underscores its stability. Understanding these parameters is crucial when planning reaction conditions or formulating products where you intend to buy 3-aminophthalic acid.

Chemically, 3-Aminophthalic Acid features both an amino group and two carboxylic acid groups on a benzene ring. This trifunctional nature makes it a versatile building block for organic synthesis. Its solubility in methanol and a pKa value of approximately 3.41 ± 0.10 provide insights into its reactivity and behavior in different solvent systems. These properties are particularly important for R&D scientists exploring new synthetic routes or optimizing existing ones. When you need to purchase 3-aminophthalic acid, having this knowledge aids in process design.

Safety and handling are critical aspects for any chemical intermediate. While specific hazard classifications may vary, compounds like 3-Aminophthalic Acid are generally advised to be handled with appropriate personal protective equipment (PPE). This typically includes gloves, eye protection (safety glasses or goggles), and protective clothing to prevent skin and eye irritation. Proper ventilation in the work area is also recommended. Manufacturers and suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., provide Safety Data Sheets (SDS) that contain detailed information on hazards, first-aid measures, firefighting procedures, and spill response, which are essential resources for any chemical professional working with the material.
