1,4-Butanediol (1,4-B, butylene glycol, or BD) is a thick, colourless liquid which is nearly odorless with a distinct bitter taste. 1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1,4-butanediol is used for the synthesis of γ-butyrolactone (GBL). In humans, it acts as a depressant and a prodrug for GHB where 1ml is equivalent to 1g of GHB. It is used as a recreational intoxicant with effects similar to alcohol. 1,4-Butanediol, as well as GBL, will dissolve most types of plastic over time. For this reason, it is recommended to only transport and store the drug using a glass container, standard gelatin capsules (not vegetarian), or high-density polyethylene plastic (also known as #2 recycled plastic). To check the type of plastic used on a bottle, one can look at the bottom for a number in the triangle shaped recycling label.
