In the dynamic B2B chemical market, procurement specialists and R&D managers are constantly seeking high-quality intermediates that can drive product innovation and enhance manufacturing efficiency. 5-Aminoisophthalic Acid (CAS: 99-31-0) stands out as a particularly valuable compound, essential for applications ranging from established dye industries to emerging advanced materials. This article provides a comprehensive look at why procuring this chemical requires a focus on quality and understanding its diverse applications.

Understanding the Chemical: Properties and Purity Standards

5-Aminoisophthalic Acid, also known chemically as 5-aminobenzene-1,3-dicarboxylic acid, is characterized by its benzene ring structure functionalized with both an amino (-NH2) group and two carboxylic acid (-COOH) groups. This dual functionality is the key to its utility. For procurement professionals, critical specifications to scrutinize when you intend to buy 5-Aminoisophthalic Acid include:

  • Assay (Purity): A minimum assay of ≥98.0% is generally expected for industrial applications to ensure predictable reaction outcomes and high-quality end products.
  • Moisture Content: Low moisture content, typically ≤1.0%, is crucial for reactions sensitive to water.
  • Physical Appearance: Supplied as an off-white to light brown crystalline powder, its form influences ease of handling and storage.
  • CAS Number: Confirming the CAS No. 99-31-0 ensures you are sourcing the correct chemical entity.

These parameters are typically detailed by reputable manufacturers and are vital for quality assurance in any B2B transaction.

Versatile Applications: From Dyes to Advanced Materials

The primary commercial application for 5-Aminoisophthalic Acid is its indispensable role as an intermediate in the synthesis of dyes. Its chemical structure facilitates the creation of dyes with excellent color intensity, stability, and durability, making it a sought-after raw material for the textile, coatings, and printing industries. Beyond this established use, the chemical’s structural attributes are attracting interest in material science. It serves as a precursor in the creation of Metal-Organic Frameworks (MOFs), porous materials with significant potential in areas like gas storage, catalysis, and separation technologies. For those venturing into these advanced fields, sourcing this compound from a dependable supplier is a critical first step.

Strategic Procurement from a Reliable Manufacturer
