Anwendungen

1,5-Pentanediol is used as a plasticizer in cellulose products and adhesives. It is used as a brake fluid additive. It reacts with 3,4-dihydro-2H-pyran to get 5-tetrahydropyran-2-yloxy-pentan-1-ol. It is also used to prepare polyesters for emulsifying agents and resin intermediates. Further, it is used in ink, toner and colorant products. In addition to this, it is used in brake fluid compositions.
