1,4-Dimethylnaphthalene（Cat No.:R022893）is an aromatic hydrocarbon consisting of a naphthalene ring substituted with methyl groups at the 1- and 4-positions. This symmetrical isomer is notable for its role in the agricultural industry, particularly as a sprout inhibitor for stored potatoes, extending shelf life by suppressing sprouting. It is also used as an intermediate in organic synthesis and materials science due to its thermal stability and hydrophobic nature. Its distinct structure imparts useful physicochemical properties for designing functionalized polycyclic aromatic compounds and studying aromatic substitution mechanisms in chemical research.
