是一种含奇数碳原子二伯羟化合物基团，有苦味,和水混溶。用作化学溶剂。在聚氨酯中可用作合成特殊聚酯及用作扩链剂。 application： 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. 1,5-Pentanediol can be used in a modified polyol process for the preparation of colloidal gold nanoparticles. It is also the starting material for preparing 1,5‐pentanediol dibenzoate.
