Beyond polymers, 1,3-Propanediol is extensively utilized as a solvent and reactant in the pharmaceutical industry. Its low toxicity profile and high solvency make it suitable for formulating various medicinal compounds. Additionally, it serves as a precursor in the production of cosmetics and personal care products, where hydration and texture modification are required.

  • Primary raw material for PTT polymer synthesis
  • Effective solvent for pharmaceutical formulations
  • Intermediate in organic synthesis routes
  • Component in cosmetic and nutraceutical products

Quality Assurance and Storage

We adhere to strict quality control protocols to ensure that every shipment meets international standards. Each batch is accompanied by a Certificate of Analysis (COA) verifying purity and physical constants. For optimal stability, the product should be stored in a ventilated, low-temperature, and dry warehouse environment. Under normal temperatures and pressures, 1,3-Propanediol remains stable, but proper handling procedures should always be followed to maintain integrity.
