Description

3-Hydroxyhomophthalic Acid is a versatile aromatic dicarboxylic acid derivative, distinguished by the presence of a hydroxyl group on the homophthalic acid core. This compound matters as a key synthetic intermediate and building block, offering unique reactivity for constructing complex molecular architectures. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries, as well as by manufacturers of advanced materials and fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with fused ring systems.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Serves as a precursor for chelating ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Polymer Chemistry: Acts as a monomer or modifier for producing specialty polyesters and polyamides with enhanced properties.
• Dye and Pigment Manufacturing: Employed in the synthesis of complex organic colorants and fluorescent markers.
• Academic and Industrial R&D: A valuable reagent for methodological studies in organic synthesis and material science.

Quality Control

Our 3-Hydroxyhomophthalic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the highest standards for purity and consistency, suitable for demanding R&D and scale-up processes. Certificates of Analysis (COA) with detailed specifications from HPLC, NMR, and other relevant techniques are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
