Description

Dipotassium 5-tert-Butylisophthalate is the dipotassium salt derivative of 5-tert-butylisophthalic acid, a high-purity organic intermediate. This compound is valued for its enhanced solubility in aqueous systems compared to its parent acid, making it a versatile building block for advanced synthesis. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for the development of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a solubilized isophthalate moiety.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where the tert-butyl group imparts specific biological activity.
• Polymer & Resin Modifier: Acts as a monomer or additive in the manufacture of polyesters, polyamides, and specialty coatings to modify thermal stability and solubility properties.
• Coordination Chemistry & Ligand Synthesis: Functions as a chelating agent or ligand precursor for metal-organic frameworks (MOFs) and catalysts.
• Research & Development: Employed in academic and industrial R&D labs for exploring new synthetic pathways and material properties.

Quality Control

Our Dipotassium 5-tert-Butylisophthalate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for industrial and research use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and handling.
