China and India are the leading exporters of 5-Hydroxyisophthalic acid (CAS 618-83-7), accounting for the majority of global shipments in recent years, while the United States, Germany, and South Korea represent the largest importing markets. Trade volumes have remained relatively stable since 2022, with modest growth in imports by European pharmaceutical intermediates manufacturers coinciding with steady 5-Hydroxyisophthalic acid prices.
5-Hydroxyisophthalic acid (CAS 618-83-7) is a white to off-white crystalline solid at room temperature, with a high melting point (~360 °C, with decomposition) and low volatility. It is an aromatic organic compound classified as a di-substituted benzenedicarboxylic acid bearing a hydroxyl group at the 5-position. Primarily used as a specialty chemical intermediate, it serves in the synthesis of high-performance polymers—including polyesters and polyimides—with enhanced thermal and mechanical properties. Its main application areas include advanced coatings, heat-resistant engineering plastics, and functional materials for electronics and aerospace components.
