2,7-Dimethylquinoline(CAS: 93-37-8)

2,7-Dimethylquinoline is a yellow crystalline solid with a molecular weight of 154.19 g/mol. It has a low water solubility (0.02 g/L at 20°C) and is soluble in organic solvents like ethanol and acetone. Chemically, it is moderately reactive towards bases and can undergo substitution reactions. Its solubility increases with increasing temperature.

2,7-Dimethylquinoline is typically synthesized by the condensation of 2-methylquinoline with formaldehyde in the presence of a strong acid catalyst such as hydrochloric acid. This reaction yields 2,7-dimethylquinoline with good selectivity and a high yield of up to 95%. Other methods include the reduction of 2,7-dimethylquinone or the treatment of 2,7-dimethylisoquinoline with sodium hydride.

2,7-Dimethylquinoline is used in various industries due to its unique properties. It is utilized in the pharmaceutical industry for the synthesis of certain drugs, in polymer production as a precursor, in the development of chemical sensors, and in semiconductor applications for doping purposes. Its versatile nature makes it a valuable compound in these fields.

When handling 2,7-Dimethylquinoline, it is essential to take appropriate safety precautions. Wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. Store it in a cool, dry place away from heat and oxidizing agents. Use a fume hood during handling and disposal, and ensure proper ventilation. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
