For chemists, formulators, and R&D scientists, a deep understanding of a chemical intermediate’s technical capabilities is crucial for unlocking its full potential. 5-Aminoisophthalic Acid (CAS: 99-31-0), with its unique molecular architecture, offers significant technical advantages, particularly in the realms of dye synthesis and material science. As a premier supplier, we aim to highlight these technical merits to assist you in your formulation work.

Molecular Structure and Reactivity: The Foundation of Performance

5-Aminoisophthalic Acid is a derivative of isophthalic acid, featuring an amino group at the 5-position of the benzene ring. This bifunctional nature is its key technical asset. The carboxylic acid groups (-COOH) allow for esterification, amidation, and salt formation, while the amino group (-NH2) can undergo diazotization, acylation, and nucleophilic reactions. This rich reactivity profile makes it an ideal building block for creating complex organic molecules. For instance, in dye synthesis, the amino group can be diazotized and coupled with other aromatic compounds to create azo dyes, known for their vibrant hues and broad color spectrum. The carboxylic acid groups can be modified to enhance solubility or binding affinity to substrates.

Key Technical Specifications for Formulation Success

When you buy 5-Aminoisophthalic Acid, several technical specifications from your manufacturer are critical for successful formulation:

  • Purity (Assay ≥98.0%): High purity minimizes side reactions and ensures the predictability of your synthesis outcomes, leading to consistent product quality in dyes or advanced materials.
  • Moisture Content (≤1.0%): Low moisture content is vital for many organic reactions that are sensitive to water, preventing hydrolysis or unwanted solvent effects.
  • Physical Form (Crystalline Powder): The crystalline nature of 5-Aminoisophthalic Acid, typically off-white to light brown, ensures ease of handling, accurate weighing, and uniform dispersion in reaction mixtures.
  • Thermal Stability (High Boiling Point/Melting Point): Its thermal resilience allows for reactions to be conducted at elevated temperatures without degradation, broadening the scope of applicable synthesis routes.

These technical parameters are not merely descriptive; they are foundational for achieving reproducible and high-yield results in your industrial processes. As a dedicated supplier in China, we ensure that our 5-Aminoisophthalic Acid consistently meets these stringent technical benchmarks.

Applications in Advanced Material Formulations

Beyond its established role in dye intermediates, the technical properties of 5-Aminoisophthalic Acid are gaining traction in cutting-edge applications. Its rigid aromatic structure and functional groups make it a prime candidate for the synthesis of Metal-Organic Frameworks (MOFs). In MOF construction, the carboxylic acid groups act as linkers that coordinate with metal ions to form porous, crystalline structures. The amino group can be further functionalized to tailor the pore environment for specific applications like gas adsorption, catalysis, or drug delivery. Researchers and developers looking to innovate in material science can purchase 5-Aminoisophthalic Acid from us for their groundbreaking projects.
