1, 3-Butanediol (otherwise called 1, 3-butylene glycol, butane-1, 3-diol, or 1, 3-dihydroxybutane) is a diol used as an intermediate chemical in the making of polyester plasticizers and different products. It discovers some use as a solvent for flavorings and as a humectant in pet nourishments, tobacco, and beautifying agents. It is one of four stable structural isomers of butanediol. In science, 1, 3-butanediol is used as a hypoglycemic agent. 1, 3 Butanediol can be changed over into-hydroxybutyrate and serve as a substrate for brain metabolism.
