CAS 504-63-2 1,3-Propanediol (1,3-PDO) with ≥99% Purity for Polymer Production and Biobased Applications

1,3-Propanediol (PDO) — Description

1,3-Propanediol (1,3-PDO) is a three-carbon, diol (two hydroxyl groups) used as a versatile intermediate and monomer in industrial chemical production. It is commonly manufactured via biobased fermentation routes (e.g., from glucose/sugars) and also via petrochemical processes. PDO is valued for enabling polyesters, polyurethanes, solvents, plasticizers, and specialty chemicals.

Specification  .

Key Features

• Two hydroxyl groups → high reactivity for polymer chemistry and formulation.
• Good solubility and miscibility with many solvents (process dependent).
• Biobased potential → supports lower-carbon product strategies.
• Low toxicity relative to many alternatives (still requires standard chemical handling).
• Versatile chemical building block for:
  • polyesters (incl. biodegradable routes),
  • polyurethanes,
  • plasticizers and specialty fluids,
  • solvents and intermediates.

Applications

1) Polymer and materials

• Polyesters (e.g., PDO-based polyesters; used for performance films and fibers)
• Polyurethanes (as a diol component affecting flexibility and hardness)
• Elastomers and coatings where diol functionality is required

2) Chemical intermediates

• Derivatives for industrial formulations, including:
  • specialty ethers/esters,
  • plasticizer intermediates.

3) Solvents / specialty formulations

• Used in formulations where diol solvents improve solubility, viscosity, and performance (varies by grade).

4) Downstream manufacturing (common value chain uses)

• Production of high-value chemical intermediates and polymer building blocks.

Packing 

Storage & Handling

Recommended storage conditions

• Store in clean, dry, sealed containers.
• Keep away from moisture (especially for polymer-grade processing).
• Maintain temperature within supplier-recommended range to prevent quality drift and minimize evaporation losses.
• Avoid contamination with acids, bases, or reactive metals unless compatibility is confirmed.

Stability / compatibility

• Generally stable under normal conditions.
• Use proper ventilation; PDO has mild odor but is still a chemical requiring routine industrial safety practices.
• Ensure grounding/bonding for bulk transfers to reduce static risk (standard practice for liquids).
