For procurement managers and R&D scientists in the chemical industry, securing high-quality raw materials is paramount. When considering 5-Aminoisophthalic Acid (CAS 99-31-0), understanding its properties, applications, and the nuances of sourcing from a reliable manufacturer is crucial. This guide aims to equip you with the knowledge to make informed purchasing decisions.

Understanding 5-Aminoisophthalic Acid: The Chemical Profile

5-Aminoisophthalic Acid, chemically known as 5-aminobenzene-1,3-dicarboxylic acid, is a bifunctional organic compound featuring both an amino group and two carboxylic acid groups attached to a benzene ring. This structure imparts unique reactivity, making it a valuable intermediate in various synthesis pathways. Typically supplied as an off-white to light brown crystalline powder, its physical form facilitates handling and integration into manufacturing processes. Key specifications to look for include a high purity assay, often exceeding 98.0%, and a low moisture content, typically below 1.0%. These parameters are critical for ensuring consistent results in downstream applications.

Key Applications Driving Demand

The primary utility of 5-Aminoisophthalic Acid lies in its role as a vital intermediate for the production of dyes. Its chemical structure allows for the synthesis of a wide spectrum of colors with enhanced stability and durability, making it indispensable for the textile, coatings, and printing industries. Beyond dyes, its potential extends to advanced materials science. Researchers are exploring its use as a precursor in the synthesis of Metal-Organic Frameworks (MOFs), which are porous materials with applications in gas storage, catalysis, and separation technologies.

What to Look for in a Manufacturer and Supplier

When you are ready to buy 5-Aminoisophthalic Acid, partnering with a reputable manufacturer in China offers significant advantages, including competitive pricing and a robust supply chain. A trusted supplier will provide detailed specifications, including CAS number (99-31-0), purity levels, and physical properties. Look for suppliers who can offer consistent quality, reliable lead times, and responsive customer service. Understanding their production capabilities and quality control measures is essential. For instance, knowing the manufacturing process, such as hydrogenation of 5-nitroisophthalic acid, can provide insight into the product's origin and quality.

Ensuring Quality and Competitive Pricing

The price of 5-Aminoisophthalic Acid can vary based on purity, order volume, and supplier. It is advisable to obtain quotes from multiple verified suppliers. When comparing prices, always consider the overall value, including product quality, packaging, and delivery. For bulk purchases or long-term supply agreements, negotiating directly with a manufacturer often yields the best results. Furthermore, inquire about their ability to provide custom packaging solutions to meet your specific storage and handling requirements.

In conclusion, 5-Aminoisophthalic Acid is a critical chemical building block with diverse applications. By focusing on product specifications, understanding its uses, and diligently selecting a reliable manufacturer and supplier, you can ensure the success of your chemical synthesis projects and material innovations.
