High purity (>99.5%) with low volatile impurities, ensuring consistent reactivity in downstream synthesis.
Optimized crystalline structure for excellent flowability and handling stability during bulk processing.
Low chloride and heavy metal content, meeting stringent requirements for high-performance resin production.
Thermally stable under standard storage conditions (≤30 °C, dry), minimizing premature hydrolysis.
Compliant with REACH and ISO 9001 manufacturing controls for traceability and batch consistency.
Primary raw material for unsaturated polyester resins (UPRs) used in marine, automotive, and construction composites.
Key monomer in alkyd resin synthesis for industrial coatings, architectural paints, and varnishes.
Intermediate in the production of plasticizers such as di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP).
Building block for dyes, including phenolphthalein and anthraquinone derivatives.
Used in pharmaceutical intermediates, e.g., in the synthesis of phthalylsulfathiazole and other heterocyclic compounds.
