1-Propanol (also propan-1-ol, propanol, n-propyl alcohol) is a primary alcohol with the formula CH₃CH₂CH₂OH and sometimes represented as PrOH or n-PrOH. It is a colourless liquid and an isomer of 2-propanol. 1-Propanol is used as a solvent in the pharmaceutical industry, mainly for resins and cellulose esters, and, sometimes, as a disinfecting agent.
