25dimethylpyridine

2,5-Dimethylpyridine, also known as 2,5-lutidine, is an organic compound with the chemical formula C7H9N. It is a disubstituted pyridine derivative where methyl groups are attached to the second and fifth positions of the pyridine ring. This compound is a colorless liquid with a characteristic pyridine-like odor. It is miscible with water and most organic solvents.

2,5-Dimethylpyridine is a weak base, similar to pyridine itself, due to the lone pair of electrons on the nitrogen atom. It can undergo typical reactions of pyridines, such as electrophilic substitution, although the presence of the methyl groups influences the reactivity and regioselectivity. The methyl groups can also be functionalized under specific conditions.

This compound finds applications as a solvent and as a building block in organic synthesis. It can be used in the preparation of pharmaceuticals, agrochemicals, and other specialty chemicals. Its specific properties make it suitable for certain reaction conditions where other pyridine derivatives might not be ideal. Due to its chemical structure, it is classified as a heterocyclic aromatic amine.
