Description

1,2,3-Benzenetricarboxylic Acid Hydrate is a versatile aromatic tricarboxylic acid derivative, also known as hemimellitic acid hydrate. This compound serves as a critical multifunctional building block and intermediate in advanced chemical synthesis, valued for its three reactive carboxyl groups. It is essential for manufacturers and R&D facilities in the pharmaceutical, polymer, and specialty chemical industries seeking to create complex molecules, metal-organic frameworks (MOFs), or high-performance polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and complex drug molecules.
• Polymer & Resin Production: Acts as a monomer or cross-linking agent for producing polyesters, polyamides, and alkyd resins, enhancing thermal and mechanical properties.
• Metal-Organic Frameworks (MOFs): Serves as a key organic linker in constructing porous MOF materials for gas storage, separation, and catalysis.
• Coordination Chemistry & Chelation: Functions as a multidentate ligand for complexing metal ions in catalysts, sensors, and water treatment processes.
• Specialty Chemical Synthesis: A precursor for manufacturing dyes, pigments, plasticizers, and corrosion inhibitors.
• Analytical Chemistry: Employed as a standard or reagent in analytical methods and research.

Quality Control

Our 1,2,3-Benzenetricarboxylic Acid Hydrate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting results for assay, water content, and residual solvents is provided and available upon request to support your quality assurance protocols.

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 absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
