Pentane15diol

Pentane-1,5-diol, also known as 1,5-pentanediol, is an organic diol with the formula C5H12O2. Its structure features a five-carbon chain with hydroxyl groups at both terminal carbons. It is a colorless, viscous liquid at room temperature and is miscible with water and many polar organic solvents.

In industry, pentane-1,5-diol is produced by catalytic hydrogenation of oxidation products derived from adipic acid or related petrochemical feedstocks; some processes use bio-based feedstocks. It is marketed as a technical chemical suitable for further conversion into polymers or as a specialty solvent.

Applications of pentane-1,5-diol include use as a monomer or co-monomer in the production of polyurethanes and polyesters. It also serves as a solvent and humectant in cosmetic formulations and as an internal plasticizer or processing aid in various polymer systems. Additional uses appear in coatings, inks, and cleaning formulations where a diol is required.

Safety and handling considerations are similar to other low-molecular-weight diols. The substance can cause irritation to skin and eyes and may be hazardous if inhaled in high concentrations. It should be handled with appropriate personal protective equipment in a well-ventilated area, stored away from heat and ignition sources, and used in accordance with the safety data sheet and relevant regulatory guidelines.
