Chemical Structure

Basic Info
The 2-methylquinoline (C10H9N), a heterocyclic nitrogen-containing compound, belongs to the quinoline derivates. The structure of 2-methylquinoline is a benzene-pyridine ring fused together with a 2-methyl substituent at the pyridine-ring’s 2 position. It is usually an oily colorless liquid, but can also be light yellow. The compound has a distinctive pyridine smell. It is only slightly soluble, but readily soluble, in water. Industrially, it can be produced by Skraup’s synthesis method, the quinoline methylation reactions, or by separation and purification of coal tar. It is a key heterocyclic intermediary in fine chemicals.
The chemical properties of 2-methylquinoline combine the alkalinity of the quinoline parent nucleus and the activity of the methyl group. Its pyridine nitrogen atom can form a coordination bond, while the methyl site is susceptible to oxidation, halogenation or condensation reactions. This structural feature makes it a multifunctional building block for the synthesis of complex heterocyclic compounds, especially in the construction of drug molecular skeletons (such as antimalarial drugs, antibacterial agents) and functional materials. In addition, its conjugated system imparts ultraviolet absorption properties and is also used as a reference substance in analytical chemistry.
