[0002] 1,2-Pentanediol is a colorless, transparent liquid that is soluble in organic solvents such as alcohol, ether and ethyl acetate. 1,2-Pentanediol is widely used around the world. In addition to being a key intermediate for the fungicide propiconazole and a cosmetic formula, it is also an important raw material for the production of polyester fibers, surfactants, pharmaceuticals and other products. 1,2-Pentanediol is a straight-chain diol with distinct polarity and non-polarity, which makes it have properties different from other diols. This special charge distribution explains its unique characteristics and versatility.
