| Common Name | (S)-Propane-1,2-diol |
|---|
| Description | (S)-Propane-1,2-diol, also known as (S)-1,2-propanediol or (S)-propylene glycol, belongs to the class of organic compounds known as 1,2-diols. These are polyols containing an alcohol group at two adjacent positions. (S)-Propane-1,2-diol is an extremely weak basic (essentially neutral) compound (based on its pKa). (S)-Propane-1,2-diol has been detected, but not quantified in, several different foods, such as common buckwheats, mustard spinach, sugar apples, black crowberries, and bayberries. This could make (S)-propane-1,2-diol a potential biomarker for the consumption of these foods. (S)-Propane-1,2-diol is a clear, colourless, viscous organic solvent and diluent used in pharmaceutical preparations. |
