4-Methyl-2-chloro-quinoline is an organic intermediate. It has been reported that it can be used to prepare graphite electrodes based on CrO-FeO-PbO and quinoline modified and a modified vermiculite adsorbent for the adsorption and removal of benzene in chemical wastewater.
The mixture of 2-hydroxy-4-methylquinoline and phosphorus oxychloride was heated to 80-85°C. After the solid was completely dissolved, the mixture was poured into ice water, the mixture was extracted with ether, and the ether extract was distilled out of ether. Afterwards, carry out vacuum distillation, collect 132-135 ℃ (0.4kPa) fraction, namely 2-chloro-4-methylquinoline. For further purification, petroleum ether (boiling point 40-50°C) can be used for recrystallization, and the yield is 86%-89%.

2-Chloro-4-methyl-quinoline is a useful synthetic intermediate. It is an intermediate used to synthesize 4-Methyl-2-(1-piperidinyl)-quinoline (M320715) which is a potent inhibitor of TRPC4 channels, responsible for various stimulation, muscle response due to interaction with the environment. 2-Chloro-4-methyl-quinoline is also considered as a cyanine dye.
