In chemistry, the n- propylphenols form a group of substances that are derived from both phenol and n- propylbenzene . The structure consists of a benzene ring with attached hydroxyl group  (-OH) and n -propyl group  (-CH 2 -CH 2 -CH 3 ) as substituents . Their different arrangement results in three constitutional isomers with the empirical formula C 9 H 12 O.

properties

3- n -Propylphenol gives iron (III) chloride in ethanol a green color, in water a bluish color. The methyl ethers, the n- propyl anisoles, are formed by methylation with dimethyl sulfate .
