What Is N-Propyl Alcohol (NPA)?
N-Propanol (also known as Normal Propyl Alcohol or 1-Propanol) is a straight-chain alcohol with the chemical formula C₃H₇OH. It is one of the propyl alcohol isomers, along with isopropanol (2-propanol), but it has a linear structure, meaning the hydroxyl group (-OH) is attached to the first carbon of the chain.
